In horses, the allele for a bay coat and the allele for a cream coat can combine to make a buckskin coat (brown with black mane, tail, and legs). The allele BB is used for bay; CC is used for cream. Buckskin horses have one bay and one cream allele BC. The genotype BC makes a buckskin coat, as both alleles are dominant.This inheritance pattern is calle

Solution
The inheritance pattern described in the question is known as Codominance. In codominance, both alleles for a gene are fully expressed in the phenotype. In this case, the bay (B) and cream (C) alleles are both dominant and when a horse inherits one of each (BC), the result is a buckskin coat. This is because both the bay and cream traits are fully expressed in the horse's coat color.

Palomino (golden brown) horses are bred for their coat coloration. A breeder will achieve 100% Palomino offspring by crossing a chestnut (dark brown) horse with a cremello (cream) horse. However, if a breeder crosses two Palomino horses, only 50% of the offspring will be Palomino, while 25% will be chestnut and 25% will be cremello. Genetic inheritance of coat color in these horses is best described as:A.codominance.B.complete dominance.C.variable expressivity.D.incomplete dominance.
