In cats, the black (B) gene has three alleles that control the density of eumelanin granules in the hair shaft. The B allele is dominant and produces a black coat. The b allele reduces black to a dark brown, chocolate color in bb homozygotes. The b' allele further reduces melanin density to produce a medium-brown coat in homozygotes called cinnamon in homozygotes. b is dominant to b' so the dominance hierarchy is B > b > b'. A mating between black and chocolate cats yields kittens of all 3 coat colors (black, chocolate and cinnamon). Use the dropdown menus to indicate parental genotypes: The genotype of the black parent was [Select] genotype of the chocolate parent was [Select] and the
