WORKSHEET (1st Meeting)
Title : Monohybrid cross
Purpose : 3.5.1 Analysing the variation in the cross.
3.5.2 Determining Ratio Phenotype and genotype as a result of cross
The following will be presented a discourse that relates to monohybrid cross. Read carefully!
Discourse 1
Besse tell you that both of them have some dominant traits in common with the ears hang,
incisors slotted and dimples. And She also tell if the mother does not have dimples like Besse.
But Besse’s aunty is none other of her mother also had a dimple, in the family of his mother,
only Besse mothers who do not have dimples. So where does Besse get Cheek Dimples are a
dominant trait? Do dimple was derived from his mother's sister ?? How did it happen ???
Sketch the diagram crosses Besse: Dimples are inherited by whom ??? in this crosses Besse in
generation????? When you have answered these questions and sketching diagrams of Besse,
check with your teacher before the end of the activity.
Discourse 3
Besse is an ornamental plant lovers. He has various types of ornamental plants. Besse crossed
one her plant with pink flowers with each other. It turns out there are descendants of red and
white flowered. Determine the genotypes of interest that crossed !! What is the nature of color on
the flower: dominant or intermediate? And how likely when the pink flowers crossed with white
flowers? Sketch diagrams in punnet square !!!
By looking at the discourse above, do things, as follows!
WS.1
1. The concepts anything related to the article!
2. Relate your hypotheses that can be used for solving the
problem!
3. Using another source of reading and answer the following
questions:
a. Write the first sound of Mendel law!
b. Determine Ratio Phenotype and genotype Filial Second (F2)
from crosses below!
1) Round eyes and slanted eyes
2) Curly and Straight hair.
4. After the group discussion did reflection and improvement of
the work then collected in the form of a report on the group
discussions
WORKSHEET (2nd meeting)
Title : Dihybrid cross
Purpose : 3.5.1 Analysing the variation in the cross.
3.5.2 Determining Ratio Phenotype and genotype as a result of cross
I. Exercise
Answer the following questions!
WS.2
1. A tall man and pointy nosed has married with a short woman with a
snub-nosed, how the comparison of offspring until his
grandchildren (F-2)?
2. A red rose with a tall stem crossed with a white rose with a
short stem. If the color of rose is intermediet and the highest of
rose is dominant, determine the ratio of offspring as a result of
that crosses.?
4. Parrots (Eclectus rotatus) with yellow colored base with a thick
wing feathers crossed with a parrot with a white base and thin
wing feathers. Determine the genotype and how the
comparison of offspring until his grandchildren (F2)?
5. In a plant species causing A dominant red colored flowers for a
white color. B gene causes the leaf width and recessive causes
small leaves. Gen C produces fruit sour and sweet fruit
recessive. Look for a wide gamete, ratio X phenotypes from
crosses AaBbCc AaBbCc!
WORKSHEET (3rd Meeting)
Title : Deviation of Mendel’s Law
Purpose : 3.5.1 Analysing the variation in the cross.
3.5.2 Determining Ratio Phenotype and genotype as a result of cross
The following will be presented a discourse that relates to monohybrid cross. Read carefully!
Discourse
“Bisu-tuli” One of the phenotypes in human that associated with hearing and speech in humans
is controlled by two genes are D genes and its allele and E genes and its allele. The existence of
two dominant gene causing the person concerned to have normal hearing and can speak with a
normal (normal people). The existence of any one dominant gene and the absence of a dominant
gene in a person, causing that person to suffer a Bisu-Tuli. Once you look at the discourse Bisu-
Tuli in Humans.
Answer the questions below. :
WS.3
1. Make a chart of a cross between a husband and wife who are
heterozygous normal until the first generation (F1).
2. How many groups of phenotypes in F1?
3. What is the ratio of phenotypes in F1?
4. Is a deaf-mute phenomenon in humans including irregularities
apparent Mendel's Law? Give an explanation!
