Nmice, black fur (b) is dominant to white (b) . at different locus, a dominant allele (a) produces a band of yellow just below the tip of each hair in mice that have black fur, which gives a frosted appearance that is termed agouti. expression of the recessive (a) allele results in a solid coat color. if double heterozygous agouti parents are crossed, what color will most of the offspring be ?
