Genes that control coat color in mammals represent some of the best early examples of genes with multiple alleles exhibiting different phenotypes. A classic example is the C gene in hamsters. Three of the known alleles of this gene are C, c^a and c^k. Each supplies a different amount of black pigment to the coat hair. The phenotypes of three different homozygous strains are as follows.

would mate the true-breeding  c^a c^a  hamsters to the true-breeding c^k c^k  hamsters to produce heterozygous  c^a and c^k  F1 progeny,  the F1 progeny cack  hamsters self fertilized, From the fraction of F2 progeny that have the wild type black phenotype, 

Crosses and their interpretation that would have allowed geneticists to come to the conclusion that ca and ck were likely to be alleles of the different gene.
