In mice, black color (8) is dominant to white (b). At a different locus, a dominant allele (A) produces a band of yellow just below the tip of each hair in mice with black fur. This gives a frosted appearance known as agouti. Expression ofthe recessive allele (a) results in a solid coat color. Ifmice
