Los genes no son todos iguales respecto a su comportamiento en la transmisión de una generación a la siguiente; existen distintos tipos de genes de los que los mejor conocidos son aquellos cuyo comportamiento fue estudiado por Mendel, por lo que reciben el nombre de genes mendelianos y la parte de la genética que se encarga de estudiarlos es la genética mendeliana.

Must know these!!! Trait—A variable characteristic of organism. It’s something about the organism’s appearance, behavior, etc., that you’re interested in. Gene—A segment of chromosomal DNA controlling a specific trait. This refers to the genetic material that produces a product that determines the trait. Locus—The chromosomal position where a specific gene lives. This is the gene’s address, in terms of which chromosome does it live on and where on that chromosome does it live? Genome—Refers to all standard loci for a species. We can speak of the “human genome.” It is the list of the genes that humans have.

Phenotype—List of traits exhibited by individual Doesn’t always reveal genotype. Sometimes the presence of a dominant allele on the maternal chromosome will mask the presence of a recessive allele on the other chromosome. Dominant—Allele that is expressed 100% in heterozygote Recessive—Allele is not expressed at all in heterozygote but only in homozygote. Incomplete dominance—heterozygote displays intermediate version of the trait about half way between the full two homozygous phenotypes.
