We call this complementary interaction. • With this type of interaction we see 2 different phenotypes instead of the 4 seen in 2 genes 1 phenotype • Two or more genotypic classes may display an identical phenotype. – Example: ...

For example, scientists have located three gene pairs (six alleles) that control eye color, and they suspect that there may be more. By tracking two of th ...

SIMULATING NATURAL SELECTION

Darwin argued, and this has subsequently been confirmed, that the primary mechanism of evolutionary change is the process of natural selection.
