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)
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

Phenotype
The set of observable characteristics or traits of an organism resulting from the interaction of its genotype with the environment.
Microscopic Characteristics
