Genetics and Mendel
... Right now there are three known gene pairs that control eye color. The bey 2 gene on chromosome 15 contains a brown and blue allele. Also on chromosome 15, the bey 1 gene is the central brown gene. On chromosome pair 19 the gey gene contains a green allele and a blue allele. A green allele is domina ...

16-2 Evolution as Genetic Change
... A. Evolution never acts directly on genes. Why? 1. It is entire organisms that either live or die a. If an individual dies without reproducing, it does not contribute its alleles to the population’s gene pool. b. If an individual produces many offspring, its alleles stay in the gene pool and may inc ...

AP Exceptions to Mendel
... Some single alleles have more than one distinguishable phenotypic effect - This is called pleiotropy. An example is the coloration pattern and crossed eyes of Siamese cats, which are both caused by the same allele. These unrelated characters are caused by the same protein produced by the same allele ...
