Introduction: I would like to nominee Gregor Johann Mendel for the "Carleton Prize for
Biotechnology". Gregor Mendel is an Australian Scientist who has been credited for discovery of
the science of genetics based on his experiments, breeding peas in the monastery garden at Brünn.
He identified the basic genetic heredity of living organism and discovered genetic through an
experiment in his garden, (Numbers, R. L. 2015). Gregor Mendel was born on July 20, 1882 in
Heinsendorf Bei Odraua, a small village in Australia (Haas, L. F.1998). Mendel's parent owned
farms for ... Show more content on Helpwriting.net ...
He also helped other colleagues at his spare time (Jay, V.2001). In spite of all obstacles in life and
many family issues, Mendel successfully graduated from the philosophy institute program in 1843,
(Soudek, D. 1984). He continued his education and became a "monk", then he went to St. Thomas
Monastery in Brno to join Augustinian order (Soudek, D. 1984). He became well known among
people as Gregor (Sorsby, A.1965). Being a master at Mendel's time was the region cutlery center,
so he got involved with people and educated them about religion (Sorsby, A.1965). He achieved the
monastery wide victory and experimental possibility. In 1849 Mendel became depressed and tired of
working with the community in Brno, then for a period of time he went to Znaim and worked as a
teacher. At that time, he failed the exam to obtain teaching–certificate. In 1851 he joined the
university of Vienna to continue master of science program. (Haas, L. F.1998) He also started
studying mathematics and physics with Christian Doppler. He studied Botany with Christian Franz
Unger, (Soudek, D. 1984). Franz was the person who used microscope during his studies. During
this time Mendel has gained different experiences in his life, earned more respect from people, and
become a well–known person (2006. PR). In 1868 he was elected as the head of the monastery for

A Monk of Science
Most people know of Gregor Johann Mendel as the Father of Genetics and the founder of heredity
principles, however, in a different angle, he is a passionate and persistent boy who allows curiosity
leads his life. Being born with a rather average background, Mendel does not let such factor to
hinderance with his dream. With his dedication and the guidance of erudite professors, Mendel is
able to conduct a research that changed history forever. According to Famous Scientists, Mendel is
born on July 1822 in a German family located at the Austrian Empire, now known as Czech
Republic. His mother is Rosine Mendel, his father is Anton Mendel and he has two sisters, the older
one named Veronica and the younger one is Theresia. The family owns a farm for more than 130
years therefore he works on the farm as a gardener while studying beekeeping at the same time.
Since he was young, nature has always been fascinating and intriguing so he uses any possible
opportunities to study which eventually mold his dream to be a scientist. In order to pursue further
education in the field, Mendel' s family actually makes sacrifices to help him financially despite
knowing how expensive it can be ("Gregor Mendel"). At the age of 18, Mendel begins his
professional academic training at a gymnasium, a school that prepares students for university, in
Opava which is quite far away from his village. Unfortunately, he needs to take a

5. Gregor Mendel As The Father Of Genetics
It is no mystery why the study of genetics came about. Homo–sapiens are one of the most
interesting creatures to figure out. The study of genetics is a great place to start of understanding
how we were brought into the form of which we are in today through the scope of biology. How we
live, how we are created, what we are composed of, and how we look like are all interesting factors
of getting to know ourselves a bit more and understanding why things are done this way. Although
for many years' scientists have had a struggle trying to discover the process behind DNA, one
succeeded. Gregor Mendel is labeled as the Father of Genetics because of his discoveries. He used
pea plants as a way to study how the traits differed. Differences in traits of the pea plants were such
as: the flower color, the pea color, or the appearance of the pea pod. He traced the segregation
between the genes of the parents with the appearance of the offspring and resulted with the traits
being either recessive or dominant. Gregor Mendel was able to distinguish inheritance patterns for
each generation, mathematically, and was able to distinguish three laws. The Law of Segregation is
the first law that is composed of pairs of alleles which are segregated during the gamete formation
process, then are reunited during the process of fertilization. The Law of Independent Assortment,
which is the second law, is when traits independently separate to give an opportunity for different
traits to occur together

7. Gregor Mendel Research Paper
Gregor Johann Mendel was a monk, teacher, and biologist. Gregor Mendel is known today as the
"Father of Modern Genetics.'' Mendel discovered the basic principles of heredity through
experiments in his monastery's garden. Gregor Mendel died on January 6, 1884, at the age of 61.
While he was born on July 20, 1822 in Hynčice Czech Republic. Gregor Mendel's observations
became the foundation of modern genetics and the study of heredity.
One interesting fact about Gregor mendel is he tried to be a teacher twice, but failed surprising from
a well known scientist. Second interesting fact about Mendel is his famous experiments were
conducted on peas.
Gregor Mendel is usually known to be the father of modern genetics. But farmers already known for
centuries that crossbreeding of animals and plants have favorable trait outcomes. Mendel's pea plant
experiments were conducted between 1856 to 1863 established many of the rules of heredity.
Mendel did his experiments at the University of Vienna, Public university in Vienna, Austria.
Around 1854, Mendel began to research the transmission of hereditary traits in plant hybrids. At the
time of Mendel's studies, it was usually accepted fact that the hereditary traits of the offspring of any
species were only the diluted mixing traits that were present in the ''parents.'' It was regularly
accepted that, over generations, a hybrid would revert to its original form, the conclusion of which
suggested that a hybrid cannot create a new forms.

9. Gregor Mendel And Marie Curie Research Paper
Born into poverty, both Gregor Mendel and Marie Curie made it very far in the world of science,
earning many degrees. I learned many interesting facts about Gregor Mendel who is the "father of
modern genetics" and Marie Curie who discovered radioactivity used for x–rays. Even though
Mendel and Curie made it very far in the world, I feel that Mendel's contributions had more of an
impact on science.
Born Johann Mendel, Gregor grew up in a family of small farmers who made financial sacrifices to
pay for his education. In 1843, Mendel's father expected him to take over the family farm, but
Mendel started studying to be a monk instead. Marie worked as a governess until she saved up
enough money at the age of 24, to buy a train ticket to Paris to begin her studies at Sorbonne. She
made ends meet by cleaning glassware in university labs. She also rationed ... Show more content on

Darwin's book "The Origin of Species" talks about how species evolve by means of mutation and
natural selection. Another way that Mendel's theory on Genetics impacts society is our food.
Genetics is used to yield better crops and the reproduction of animals. Marie Curie identified both
polonium and radium in 1898 and describe the elements as "radio–active." Marie and her husband
Pierre shared the Noble Prize in physics with Becquerel in 1903. And in 1911, she received a second
Nobel Prize, this time in Chemistry.
In conclusion, Mendel and Curie both had a positive impact on the world of Allied Health. Mendel's
work with pea plants contributed to the Allied Health field by giving the fundamental laws of
genetics. Radioactivity that Curie helped discovered led to new therapeutic and diagnostic methods
in medicine. Mendel's experiments led to a greater understanding of genetics. As you can see,
Mendel had a greater impact on society because his laws about genetics affects our crops, our own

11. Gregor Mendel Essay
Gregor Mendel played a huge role in the underlying principles of genetic inheritance. Gregor was
born, July 22 1822 in Heinzendorf, Austrian Silesia (now known as Hyncice, Czech Republic), with
the name Johann Mendel. He changed his name to Gregor in 1843. He grew up in an Augustinian
brotherhood and he learned agricultural training with basic education. He then went on to the
Olmutz Philosophical Institute and later entered the Augustinian Monastery in 1843. After 3 years of
theological studies, Mendel went to the University of Vienna, where 2 professors influenced him;
the physicist Doppler and a botanist named Unger. Here he learned to study science through
experimentation and aroused his interest in the causes of variation in plants. ... Show more content

This hypothesis can be divided into four main ideas. The first idea is that alternative versions of
genes account for variations in inherited characters. Different alleles will create different variations
in inherited characters. The second idea is that for each character, an organism inherits two genes,
one for each parent. So that means that a homologous loci may have matching alleles, as in the true–
breeding plants of Mendel's P generation (parental). If the alleles differ, then there will be F hybrids.
The third idea states that if the two alleles differ, the recessive allele will have no affect on the
organism's appearance. So an F hybrid plant that has purple flowers, the dominant allele will be the
purple–color allele and the recessive allele would be the white–color allele. The idea is that the two
genes for each character segregate during gamete production. Independent assortment states that
each member of a pair of homologous chromosome segregates during meiosis independently of the
members of other pairs so that alleles carried on different chromosomes are different distributed
randomly to the gametes. Mendel's work was not recognized
right away as an important scientific breakthrough. In 1868 Mendel was promoted to abbot at the
monastery and gave up his experiments. Aside from his fellow monks and his students his work was

13. Gregor Mendel : Basic Principles Of Heredity
Gregor Mendel discovered the basic principles of heredity. His observations became in the
foundation of modern genetics. He was born in Austria in 1822. Mendel graduated from the school
with honors, in 1840. Later, his graduation, Mendel enrolled in a two–year program at the
Philosophical Institute of the University of Olmütz. He again distinguished himself academically,
especially in the subjects of physics and math. In 1843, Mendel began studying to be a monk at the
St. Thomas Monastery in Brno, the Augustinian order. This monastery was a cultural center and
Mendel gained access to the monastery's library and experimental facilities. In 1851, he was sent to
the University of Vienna, to continue his studies in the sciences. While Mendel studied mathematics
and physics under Christian Doppler, he started studied botany under Franz Unger, who had begun
using a microscope in his studies. In 1853, after completing his studies at the University of Vienna,
he returned to the monastery and was given a teaching position. In this position, he would stay for
more than a decade; during this time that he began the experiments for which he is best known. He
was the first person to trace the characteristics of successive generations of a living thing. He loved
the nature and he decided to investigate about it. He was not only interested in plants, but also in
theories of evolution. Mendel wondered how plants obtained atypical characteristics. In 1854,

15. Analysis Of Gregor Mendel 's The Mid 1800 ' S
Before Gregor Mendel's discoveries in the mid 1800's, most people had no clear idea as to why their
children, and grandchildren, looked like them! Most people assumed that because the child was in
their family, and created by them, that familiar looking offspring just simply happened. Gregor
Mendel put all that guessing to rest. Mendel did experiments on two different colored pea plants. In
the first test, he mixed a purple flowered pea plant, and a white flowered pea plant. He let these
plants fertilize and have off spring. These two plants were known as the Parent generation (P
Generation). The offspring they produced were known as the F1 Generation. The P Generation
created an F1 Generation that was all purple pea plants. Mendel then bred a new generation of pea
plants ONLY breeding plants with themselves. This new generation was known as the F2
Generation. Within the F2 Generation, the white flowered pea plants began to show back up. The
ratio of purple flowered pea plants, to white flowered pea plants was a 3:1 ratio. Mendel also noted
that the purple and white color had not been blended; the white color was just purely masked by the
purple color in the F1 Generation. Mendel was then able to make conclusions about simple
breeding. He called the purple flowers dominant, because they were more frequent than the white
flowers. He called the white flowers recessive, because they were less frequent than the purple
flowers. Therefore he concluded that the purple flowers were

Mendelian Inheritance in Brassica Rapa Gregor Mendel, also known as the "father of modern
genetics," revolutionized the world 's understanding of the inheritance of traits when he
experimented with various pea plants over multiple generations. In performing this experiment, he
discovered the law of independent assortment and law of segregation. The Law of independent
assortment states that genes located on separate chromosomes segregate independently of each
other. The law of segregation states that two alleles segregate at different gametes so that each
gamete receives only one allele. Brassica Rapa plants were developed by Dr. Paul Williams and a

plants were not given water. During the following week, the flowers were opened and the seeds
were collected from the dry seed pods. These were the seeds which were used to germinate the F2
generation. After the seeds were harvested, they were aloud to dry for one week. Paper towels with
grids drawn upon them were laid out on the germination container and then the seeds were placed in
each box. The seeds were sprayed using a spray bottle and then covered with the germination
container top. A picture of Brassica Rapa is shown to the right:

He was more than a son of farmer, scholar and monk. He was the epitome of what great scientists
strive to be. Mendel was diligent in testing his ideas and studious in writing concerning the
outcomes. We may never know the full extent of his discoveries due to the fact that fellow monks
burned many of his writings at his death. A few documents still exist in his own writing. If scientist
and doctors can use his methods to predict certain medical outcomes and predispositions, they may
be able to save lives. It's amazing to think that the work of one man, who in the solitary of a
monastery, could have such vast impact. If one life can be saved through genetic testing, then
Mendel should be given much accolades for his part in today's life changing discoveries. Gregor

While studying pea plants, Mendel realized that basic underlying principles of heredity found in pea
plants could also apply to more complicated life forms like humans and animals and essentially
discovered genetics. By selectively breeding and observing the seven factors of pea plants over
multiple generations, Mendel found that invisible ''factors'' now known as genes provide ''visible and
nonvisible traits in predictable and observable ways'' (Landry). Mendel found that, when breeding a
purebred white flowered pea plant with a purebred pea plant with purple colored flowers, the
offspring had purple colored flowers rather than a mix of the two. He also discovered that alternative
forms of these genes existed, these are later called alleles. Mendel created three scientific laws from
his findings. Mendel's Law of Segregation states that the alleles of a gene separate from each other
during a process called gamete formation. Mendel's Law of Independent Assortment states that
genes of different traits can separate independently during this process. Mendel explains that alleles
can be dominant or recessive and that an organism with at least one dominant allele will show the
dominant trait. This is explained in his Law of Dominance. A common theory at the time was that
traits were present in all generations but Mendel postulated that traits can be recessive or dominant
when he observed the phenomena of traits not appearing in one generation but

Introduction
Gregor Johann Mendel was a scientist, Augustinian friar and an abbot of St. Thomas' Abbey in
Brno, Margraviate of Moravia. He was born on July 20, 1822 and died on January 6, 1884 at the age
of 61. He was Austrian and was the child of Anton and Rosine Mendel along with two other
siblings. He studied in the field of genetics at two universities and one institution and is known for
creating the science of genetics.

Some of these characteristics were the height of the plant, shape of the pod, shape of the seed, size
and color of the seeds. He cross–pollinated the plants with different characteristics in order to study
the effects on the offspring. He also made sure to prevent accidental pollination by insects. He
cultivated thousands of pea plants throughout his experiments. He collected the seeds of the
offspring and examined them for changes or variations in color, shape, and size. He compared the
plants for differences in height. Over a period of eight years he examined and observed plants that
would form the basis for a deeper study of genetics. He presented the results of his experiments in
1865 at the Natural History Society of Brno. In 1866 his findings were published in 'Experiments on
Plant Hybridization.' His research failed to create an impact at that time. He was made abbot of the
monastery in 1868, where he had been teaching. The increase in responsibilities prevented him from
carrying out anymore scientific experiments. Gregor Mendel's experiments and information failed to
gain much attention and importance during his lifetime, but he did form the foundation for what is
now known as Mendel's Laws of Inheritance.

After he became the abbot of the monastery, he stopped with his science work and experiments
because he was consumed with his responsible as the abbot, especially when he disputed with the
civil government when they tried to impose special taxes on the religious institutions.
Gregor Mendel conducted many experiments. He was inspired by his professors at the Palacky
University in Olomouc, and his colleagues at the monastery to study variation in plants. C. F. Napp
authorized Mendel for his investigation. Mendel conducted his studies in the monasteries 4.9 acres
of experimental garden. Napp planted this garden originally. Unlike Nestler who studied hereditary
traits in animals like sheep, Mendel focused on studying the hereditary traits of plants. After he
initially experimented with pea plants, he settled on studying seven traits that seemed to inherit
independently over other traits. Mendel focused on seed shape, which was angular or round.
Between 1856 and 1863 Mendel experimented and tested some 28,000, most of those plants were
pea plants. His studies showed that one in four pea plants had purebred recessive traits, two out of

genetics.tic research began with Gregor Mendel the "Father of Genetics". He had performed an
experiment with plants in 1857 that led to increased interest in the study of genetics.
ORIGIN OF DNA
DNA started way back in 1868 by a physician named Friedrich Miescher. For a long time, the
connection between nucleic acid and genes was not known, but in 1944 the American scientist
Oswald Avery was able to prove that genes were made up of nucleic acid. The first person to find
out about the structure of DNA or (deoxyribonucleic acid) truely was a women. Her name was
Rosalind Franklin, she found the structure of DNA. But her work were stolen by two men, they go
by Francis Crick and James Watson (Lloyd,2010). They soon got a Nobel Prize for their work.

33. Examples Of Gregor Mendel Theory Of Genetics
I. Introduction In this lab we considered Gregor Mendel theory of genetics. Mendel was a botanist
and statistician. Mendel worked with garden peas to figure out their genetic pattern. The peas were
also true–breed.1 The three principles that Mendel had for inheritance pattern are the principle of
segregation, principle of dominance, and principle of independent assortment.2 The first principle of
segregation means that the individual gets part of the trait from each parent that makes their traits.2
The second principle of dominance is that a trait may be present during the first generation, but
doesn't not mean it could be present in future generations and that the dominant allele is showed.
The third principle of independent assortment is that it depends on the different units that are passed
on that can decide your traits based on other traits that are given.2 This now goes into showing that
variation of a gene is called an allele. This is now shown in a phenotype and genotype. A phenotype
is showing he physical trait that we can see. A genotype is the showing of the genetic form that
made that trait.3 Another term we used in this lab was homozygous which means you have two of
the same alleles. The next term that was used is heterozygous which means that two different alleles
were used. The term that was important that we used was a Punnett square. A Punnett square is way
to be able to calculate the different potential outcomes of the genotypes graphically.3

35. How Did Gregor Mendel Changed The World Of Genetics
Gregor Mendel was born in Austria of 1822. His parents were mostly farmers where he spent most
of his time outside. He became very interested in plants, trees, and fruits. As Mendel grew older, he
became an Augustinian monk and a botanist. A botanist is a person who studies in the field of plants.
("Early Life" 2016 para 3) During this time, Mendel was able to conduct his famous experiment. His
work was not confirmed until the 1900's when three scientists, Erich Tschermak, Hugo de Vries, and
Carl Correns verified it. This was the beginning of Mendel's experiment that changed the world of
genetics forever ("Gregor Mendel" 2003–2016, para 3). Mendel chose to use pea plants for his

Our hair color is determined on how our parents hair color is. For example, if both of your parents
were homozygous dominant for brown hair, the probability of your hair color to be brown is one
hundred percent which also makes you homozygous dominant. Yet, if one of the parents were
heterozygous for blonde hair, the child would have a possibly chance to have blonde hair instead of
brown. But in order to figure out why we have similar characteristics as our parents and siblings,
Mendel decided to use a punnett square to see the different offspring. Instead of finding why we
have similar characteristics as our family, Mendel tested this on pea plants instead. He crossed tall
and short pea plants of the parents to see the first generation of children. In order to do this, he used
an abbreviated allele code for tall (TT) and another for short (tt). The punnett square helped give us
a visual picture of what Mendel was doing which supported Mendel's Law of Dominance. In
conclusion, Mendel chose to use pea plants for his experiment because they reproduce quickly, he
developed laws that formed the foundation of modern genetics, and he chose different traits to help
support the idea of his experiment. Mendel's experiment is important because we can see why traits
skip generations and how others are getting discrete traits. His experiment is also important in the

Gregor Johann Mendel was a researcher, Augustinian minister and abbot of St. Thomas' Abbey in
Brno, Margraviate of Moravia. Mendel was naturally introduced to a German–talking family in
Silesian part of the Austrian Empire and increased after death acknowledgment as the author of the
cutting edge study of hereditary qualities. In spite of the fact that ranchers had known for quite a
long time that the crossbreeding of creatures and plants could support certain attractive
characteristics, Mendel's pea plant tests led in the vicinity of 1856 and 1863 set up a large portion of
the tenets of heredity, now alluded to as the laws of Mendelian legacy. Mendel worked with seven
qualities of pea plants: plant tallness, pod shape and shading, seed shape ... Show more content on

quantitative impacts. Charles Darwin attempted unsuccessfully to clarify legacy through a
hypothesis of pangenesis. It was not until the mid twentieth century that the significance of Mendel's
thoughts was figured it out. By 1900, inquire about went for finding an effective hypothesis of
spasmodic legacy instead of mixing legacy prompted to free duplication of his work by Hugo de

Gregor Mendel discovered the fundamental laws of inheritance. He chose pea plants as his
experimental organism and carried out self–fertilization experiments. Mendel's laws are the law of
segregation and the law of independent assortment. Mendel's law of segregation says that the two
copies of a gene separate from each other during transmission from parent to offspring. When an
individual possessed two identical copies of a gene, the individual is said to be homozygous with
respect to that gene. Using Mendel's cross of tall and dwarf pea plants to illustrate how genes are
passed from parent to offspring, the letters T and t are used to represent the alleles of the gene that
determines plant height. In the P cross, the tall plant is homozygous

Introduction Who was Gregor Mendel? Gregor Mendel was know as the "father of genetics".
Mendel was an Austrian monk and biologist. He was born July 22, 1822 in Heinzendorf, Austria.
Mendel's became the founder of modern genetics and the study of heredity, using experiments in his
monastery's garden. His experiments shows that the inheritance of certain trait of a pea plant that
follows particular patterns. This became the foundation of modern genetics and leading the study of
heredity.

In 1853, after completing his studies at the University of Vienna, Medel returned to Brno and was
given a teaching position and he would stay there for more than a decade. It was during this time
that Mendel began the experiments for which he is best known for.
Experiments and Findings/Conclusion In 1854, Mendel he began his researching on the
transmission of heredity traits in plant hybrids. During this time, it was an accepted fact that the
heredity traits of the offspring of any species were merely the diluted blending of the traits that were
present in the "parents." Over the generations, a hybrid would revert to its original form, the
implication which suggested that a hybrid couldn't create any new form/forms. Even though that
happened, the results of the studies were often skewed by the relatively short period of time during
the experiments. Mendel's research continued for about 8 years and involved tens of thousand of
individual plants In his experiment, Mendel chose to use pea plants due to their man distinct
varieties and also because the offspring could be quickly and easily produced. Mendel cross–
fertilized the pea plants that had opposite characteristics and after analyzing the results, he reached
two of his most important conclusions: the Law of Segregation, which established that there can be
dominant and recessive traits passed on randomly from the parents to their offspring, and the other
conclusion was the Law of Independent

Gregor Mendel
"The Genius of Genetics"
BACKGROUND
Gregor Mendor was born the second of three children to Anton and Rosine Mendel on July 22, 1822
in Heizendorf (the Czech Republic. His given name was Johann. He was the son of a farmer who
owned his own land and taught his son the value of hard work. The two of them spent many hours in
their orchard and garden. This is where much of his learning began. During his youth, Mendel
studied science, plants and beekeeping He continued to excel in school and graduated with the
highest honors from high school at age 18. Because his family was poor, Mendel struggled to
complete his education. His sister contributed to help further his studies until he could find work. He

His work made it possible for the first time to exploit the genetic resources of organisms
systematically. Mendel's name marks not only the beginning of genetics as a discipline, but also the
beginning of the systematic use of mathematics, qualified measurements and applied statistics in
biology.
HOW WORK WAS VIEWED BY CONTEMPORARIES There was little reaction to Mendel's early
discoveries from the scientific community. After eight years of carrying out experimental work in
the monastery garden, he shared his findings in several monthly meetings of the Natural Research
Association. Mendel published his lecture, a work that was to establish him as "the father of
genetics". Several offprints were sent out, but these were ignored. The importance of Mendel's work
was recognized only 34 years after his work ended. In 1900 Mendel's Laws were rediscovered by
Carl Correns in German, Hugo de Vries in the Netherlands and Erich von Tschermak–Seysenegg in
Austria.
HOW HIS WORK IS VIEWED TODAY Mendel's work started a science about heredity. This new
science became known as genetics. Scientists began to discover from Mendel's papers the laws he
discovered of Segregation and Independent Assortment. Mendel's observation s and outstanding

on religious institutions.[14] Mendel died on 6 January 1884, at the age of 61, in Brno, Moravia,
Austria–Hungary (now Czech Republic), from chronic nephritis. Czech composer Leoš Janáček
played the organ at his funeral. After his death, the succeeding abbot burned all papers in Mendel's
collection, to mark an end to the disputes over taxation.[15]
Experiments on plant hybridization
Dominant and recessive phenotypes. (1) Parental generation. (2) F1 generation. (3) F2 generation.
Gregor Mendel, who is known as the "father of modern genetics", was inspired by both his
professors at the Palacký University, Olomouc (Friedrich Franz and Johann Karl Nestler), and his
colleagues at the monastery (such as Franz Diebl) to study variation in plants. In 1854, Napp
authorized Mendel to carry out a study in the monastery's 2 hectares (4.9 acres) experimental
garden,[16] which was originally planted by Napp in 1830.[13] Unlike Nestler, who studied
hereditary traits in sheep, Mendel focused on plants.
Mendel carried out his experiments with the common edible pea in his small garden plot in the
monastery. These experiments were begun in 1856 and completed some eight years later. In 1865,
he described his experiments in two lectures at a regional scientific conference. In the first lecture he
described his observations and experimental results. In the second, which was given one month
later, he explained them.
After initial experiments with pea plants, Mendel settled on studying seven traits that seemed to be
inherited independently of other traits: seed shape, flower color, seed coat tint, pod shape, unripe
pod color, flower location, and plant height. He first focused on seed shape, which was either
angular or round.[17] Between 1856 and 1863 Mendel cultivated and tested some 28,000 plants, the
majority of which were pea plants (Pisum sativum).[18][19][20] This study showed that, when true–
breeding different varieties were crossed to each other (e.g., tall plants fertilized by short plants),
one in four pea plants had purebred recessive traits, two out of four were hybrids, and one out of
four were purebred dominant.

while he was alive he was not recognized for any of his works with research. He was born in Austria
in 1822 and his parents were agriculturalists. As a young child his family lived and owned a farm,
Mendel became very intrigued with plants, shrubbery, and produce. As he grew older he absolutely
loved to learn and was spiritual, he soon moved away from home. Over the course of his lifetime he
became a professor, minister, and researcher. While Gregor was a monk, he was able to nurture and
take care of the garden at the monastery. He was responsible for the Laws governing Inheritance of
Traits. Mendel planted and tested some 28,000 pea plants, he discovered that the plants ' progeny
reserved traits of the parents. Mendel piloted his experiment using empirical probability from 1856
to 1863. Probabilities are mathematical measures of likelihood. The empirical probability of an
event is planned by dividing the number of times the event occurs by the total number of chances for
the event to occur. (Empirical probability – Wikipedia, the free encyclopedia:, n.d.). Mr. Mendel was

When born, fruit flies are sheltered in an oval shaped egg and can be seen with the naked eye. After
approximately a day or two, the larva erupts from its shell, immediately looking for any source of
food. They have a tendency to tunnel through objects. They shed continuously until they become a
mature larva. Once the mature larva becomes a pupal, it usually climbs on the cultural bottle they
are sealed in and form a pupal case. In there, the pupal must go through the stages of metamorphosis
until they become a male fruit fly. Once an adult fly, the eyes, wings, and legs become visible with
the naked eye. Like peas, they do not have a long life span and can reproduce very quickly. They
need little food, occupies minimal space, and have many types of genetic variations that can be seen

By using maths and statistics, he was able to determine an average, for every three purple flowers
one white flower will occur, a ratio of 3:1.
Gregor Mendel first wanted to achieve a pure breed of flowers, but also wanted to observe the
outcome by crossing the white and purple flowers. For this, we have to understand the basic
principle of how the pea plant fertilizes itself. The stamen is the male part of the plant. The stamen
of the plant is drop pollen into the plant when the start to mature. The pollen falls upon the pistil,
which is the female region of the plant. It then fertilizes the plant and becomes matured plant.
However to cross–fertilize the pea plants Gregor Mendel used a slightly different method whereby
he opened an immature pea plant. Mendel then took out the stamen before they could become
mature and drop pollen upon the pistil. Thereafter using the pollen, which he had taken out, he then
dusted and brushed the pollen on to the pistil of another pea plant transferring them with the aid of a
small brush. The cross–fertilizing of the two plants was named as the parental generation (P) as they
were the first to be pollinated and fertilised.
He transferred and cross–fertilized pea plants, which only had white and purple flowers. He was
very careful within his experiment and insured the controls were accurate and precise at all time.

No one really understood the genetic principles of these plants and animals so the experiments were
sometimes dangerous and costly. In the 1890's better microscopes were introduced into the scientific
world and allowed scientist to further their study and knowledge in cell division. This was a key
component in the study of genetics. Mendel is commonly known at the "father of modern genetics".
While being a teacher Mendel had time to have experiments of his own. Most of his time was spent
on the testing of pea plants. He tried to use regular garden pea plants because they were easily
accessible, grown in large numbers in the monastery gardens, and they were extremely easy to
reproduce while not having to wait a long period of time before receiving results. Common pea
plants have both male and female reproductive organs which gives them the ability to either self–
pollinate or cross–pollinate.
The experiments were to study their genetic makeup and test them over generations and generations
of other pea plants. He would study a "parent" plants and when their offspring appeared he noticed
that only certain characteristics would show up in their offspring. "For instance, the pea flowers are
either purple or white– intermediate colors do not appear in the offspring of cross pollinated pea
plants. Mendel observed seven traits that are easily recognized and apparently only occur in one of

This law involves inheritance of biological features. In 1915 Mendel 's theories were integrated with

core of classical genetics. Then in 1930 Ronald Fisher combined them with the theory of natural

Law of Independent Assortment
The Law of Independent Assortment states that alleles for separate traits are passed from parents to
offspring independently from each other. Proof of this principle was achieved through dihybrid and
monohybrid cross experiments. Independent assortment occurs in eukaryotic organisms during
meiotic metaphase I, and produces a gamete with a mixture of the organism 's chromosomes. The
physical basis of the independent assortment of chromosomes is the random orientation of each
bivalent chromosome along the metaphase plate with respect to the other bivalent chromosomes.
Along with crossing over, independent assortment increases genetic diversity by producing many
genetic combinations.
Law of Dominance
Mendel 's Law of Dominance states that recessive alleles will always be masked by dominant
alleles. This means a cross between a homozygous dominant and a homozygous recessive will
always express the dominant phenotype whilst still having a heterozygous genotype. Proof of this
principle was achieved using a mono hybrid cross experiment: In a cross between two organisms of
contrasting traits the trait that is expressed is called "dominant" and the trait that is suppressed is
called "recessive."

with different variations of a similar trait were cross bred, the offspring would only display one of

74. The Common Fruit Fly By Gregor Mendel
Abstract:
The basis of genetics were established by Gregor Mendel, an Augustinian monk in the mid to late
1800's. Through the observations from cross–pollinating pea plants, Mendel was able to discover the
basic laws of inheritance. Years later genetics would be studied on a multitude of organisms, some
more than others. Drosophila melanogaster or the common fruit fly has been studied in depth for its
great advantages, such as size, reproduction rate, ease of care and inexpensive room and board.
In this experiment we tested to see what the offspring of an unknown cross of an F1 generation
would produce. After observing the F2 generation and recording the data we found some of the
Drosophila showed mutations, two in particular. The mutations were the apterus wings, and sepia
eyes. After collecting our data through observation, a Chi–test was conducted resulting in a Chi–
value of 5.1 and a p–value of .2. Since the p–value was greater than 0.05, there was no significant
change in the data. This proved that the Drosophila flies still followed the Mendelian genetics of a
9:3:3:1 ratio.

Gregor Mendel in 1865 during his studies of genetics in pea plants. Two identical forms one has two
yellows the other has two greens. The principle of segregation and the principle of independent
assortment. Some biologists refer to Mendel's "principles" as "laws". Most of the leading scientists
in the 19th century accepted this " blending theory" that he had
