An Example of Epistatic Interaction between Genes

Caption

Coat color in Labrador retrievers is due primarily to epistatic interactions between two genes. One gene determines whether the dog has a dark or yellow coat. The second gene determines whether the darker dogs will be black or chocolate labs (and whether yellow labs have brown or pink noses).
