When roan cattle are mated 25 of the offspring are red 50 are roan and 25 are white. Upon examination it can be seen that the coat of a roan cow consists of both red and white hairs. This trait is one?

The coat color of roan cattle demonstrates a classic case of codominance in genetics, where both red and white alleles are expressed equally, resulting in the roan phenotype. The observed offspring ratio of 25% red, 50% roan, and 25% white aligns with Mendelian inheritance, indicating that both parent roan cattle likely carry one allele for red and one for white. This genetic interaction leads to the distinct appearance of roan cattle, which exhibit a mix of both hair colors.
