Mice have a set of multiple alleles of a gene for coat color
Four of those alleles are as follows:
C = full color (wild)
cch = chinchilla
cd = dilution
c = albino
Given that the gene locus is not sex-linked and that each allele is dominant to those lower in the list, diagram the crosses indicated below and give the phenotypic ratios expected from each.
(a) wild (heterozygous for dilution) × chinchilla (heterozygous for albino)
(b) chinchilla (heterozygous for albino) × albino
(a) Ccd × cchc ? 2 full color:1 chinchilla:1 dilution
(b) cchc × cc ? 1 chinchilla:1 albino
