Question

Inheritance of the palomino coat color in horses is a result of incomplete dominance. White horse is DD, a chestnut horse is dd, and a palomino horse is Dd. What is the expected percent of coat colors in the offspring of two palomino horses?

Answer 1

The expected percent of coat colors in the offspring of two palomino horses can be determined using the principles of incomplete dominance. The expected percentages are 25% white, 50% palomino, and 25% chestnut.

Step-by-step explanation:

The expected percent of coat colors in the offspring of two palomino horses can be determined using the principles of incomplete dominance. When two palomino horses (Dd) are crossed, there are three possible genotypes: DD, Dd, and dd. Each genotype represents a different coat color. DD (white horse) and dd (chestnut horse) are the homozygous genotypes, while Dd (palomino horse) is the heterozygous genotype. The expected percent of coat colors in the offspring will be 25% white (DD), 50% palomino (Dd), and 25% chestnut (dd).
