Horses have three basic coat colors: red (or chestnut), bay, and black. All the colors are controlled by the interaction of two genes, Extension (E) and Agouti (A). The following combinations produce bay color: EE/Aa, Ee/Aa, EE/AA, Ee/AA. Only two produce black color: EE/aa, Ea/aa. Other combinations of the alleles of these genes plus mutations of others result in many possible coat colors and patterns in horses.

GPT-4o mini · Answer

Coat color in horses, as described by the interaction of the Extension (E) and Agouti (A) genes, is an example of Mendelian inheritance. This is because it follows specific patterns of inheritance defined by dominant and recessive alleles, as noted in the combinations that produce different colors (bay, black, and chestnut).

So the correct answer is: Mendelian inheritance.
