In mice, there is a set of multiple alleles of a gene for coat color. Four of those alleles are as follows:
C = full color (wild type) 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, give the phenotypic ratios expected from the following cross. wild (heterozygous for dilution) × chinchilla (heterozygous for albino) A) 1 chinchilla : 2 dilution : 1 albino B) 2 full color : 1 chinchilla : 1 dilution C) 1 full color : 1 chinchilla : 2 dilution : 1 albino D) 1 full color : 1 chinchilla : 1 dilution : 1 albino E) 2 full color : 2 chinchilla : 1 dilution
