Question

In horses, some of the genes for hair color are incompletely dominant. Phenotypes are brown, white, and yellow-tannish called palomino. Brown hair is homozygous dominant, white hair is homozygous recessive, and palomino is heterozygous. What are the genotype and phenotype ratios for a brown female and a white male?

Answer 1

The genotype of a brown female horse would be BB, and the genotype of a white male horse would be cc. The phenotype of both horses would match their genotypes.

Step-by-step explanation:

The genotype of a brown female horse would be BB, and the genotype of a white male horse would be cc. The phenotype of both horses would match their genotypes, so the brown female would have brown hair and the white male would have white hair.

The genotype ratio for the brown female and white male would be 1:0, as the brown female is homozygous dominant while the white male is homozygous recessive. The phenotype ratio would also be 1:0, as both horses display their respective dominant and recessive traits.
