One example of a single gene effect trait in animal breeding is coat color in cattle. Coat color is controlled by a single gene, and there are multiple alleles that determine the color variation. For example, in cattle, the gene responsible for coat color is called the MC1R gene. The different alleles of this gene result in animals having different coat colors such as black, red, or brown. By selectively breeding animals with specific coat colors, breeders can control and produce desired coat colors in their cattle populations.
