The coat color in horses represents polygenic inheritance. This is because multiple genes (Extension and Agouti) interact to determine the coat color, resulting in a variety of colors and patterns based on different allele combinations.
Horses have three basic coat colors: red (or chestnut), bay, and black. All the colors are controlled by the interaction of two genes, called Extension (E) and Agouti (A). The following combinations produce the bay color: EE/Aa, EeAa, EE/AA, and Ee/AA. Only two produce black color: EE/aa and Ea/aa. Other combinations of the alleles of these genes plus mutations of other genes result in many possible coat colors and patterns in horses.
