Date: Name: Practice: Incomplete and Codominance + In horses, the allele for a bay coat (brown with black mane, tail and legs) and the allele for a cream coat can combine to make a buckskin coat. The allele CB is used for bay: CCR is used for cream. Buckskin horses have one bay allele and one cream allele. The genotype C CCR makes a buckskin coat, as neither allele is dominant Buckskin 1. Cross a bay stallion with a cream mare. List all offspring phenotypes as a percentage. Show your work with a Punnett square.​
