Provide a brief definition of the terms additive variance, dominance variance, and interactive variance
What will be an ideal response?
Additive variance results from the average effect of additive genes. Dominance variance accounts for variation when phenotypic expression in heterozygotes is not precisely intermediate between the two homozygotes. Interactive variance occurs when two or more loci behave epistatically.

The height at which green anoles and brown anoles perch in trees overlaps a bit. When brown anoles were introduced to islands inhabited by green anoles, the green anoles evolved a higher number of specialized toe scales in order to perch higher than they previously did when they were the sole species on the island.
