Chestnut Horse Genetics and Characteristics

The video lecture discusses chestnut horses, focusing on their base coat color and various shades, including Sandy, Sorel, and Liver Chestnut. It explains the genetic inheritance of the chestnut color, emphasizing the role of recessive alleles. The lecture also covers the flaxen trait, which results in lighter mane and tail colors, and highlights horse breeds like Suffolk Punch and Haflinger that commonly exhibit chestnut coloring.
