Question

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.Coat color in horses is an example of which type of inheritance?(1 point)Responsesdominant inheritancedominant inheritancerecessive inheritancerecessive inheritancepolygenic inheritancepolygenic inheritanceMendelian inheritance

Answer 1

Mendelian inheritance.

Reason: coat color here is determined by distinct alleles at two Mendelian genes (E and A) with dominant/recessive interactions (including epistasis), not by many additive genes (polygenic).
