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.

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?

polygenic inheritance
polygenic inheritance

dominant inheritance
dominant inheritance

Mendelian inheritance
Mendelian inheritance

recessive inheritance

Answer 1

Coat color in horses is an example of Mendelian inheritance. Mendelian inheritance refers to the patterns of inheritance that follow the principles described by Gregor Mendel, often characterized by the presence of dominant and recessive alleles. In this case, the coat color is controlled by the interaction of two genes and their alleles (Extension and Agouti). The combinations of these alleles determine the coat color, with some alleles being dominant over others.
