Coat color in mice involves the effects of multiple gene interactions.If a mouse has two recessive alleles (aa) for coat color, it will always be albino no matter what the genotype of other genes involved in coat color.This is an example of
A) pleiotropy.
B) incomplete dominance.
C) codominance.
D) heterosis.
E) epistasis.

Question

Quizplus · Accepted Answer

This is an example of epistasis, where one gene (the gene for albinism in this case) masks or suppresses the expression of another gene at a different locus, determining the coat color regardless of the other genes' configurations.
