... For example, in mice and many other mammals, coat color depends on two genes. One, the epistatic gene, determines whether pigment will be deposited in hair or not. Presence of pigment (C) is dominant to absence of pigment (c). The second gene determines whether the pigment to be deposited is black ( ...
