Equine Coat Color Genetics Base Coat Color The basic coat colors of horses include chestnut, bay, and black. These are controlled by the interaction between two genes: Melanocortin 1 Receptor (MC1R) and Agouti Signaling Protein (ASIP). Horses come in many colors, all of which are controlled by genetic variation in one or more genes within the horse's genetic makeup.
Properly identifying coat colors and knowing how each of these genes influence coat color is important to consider when breeding responsibly. Knowing and applying a horse's coat color genetics in combination with other genetic factors when selecting breeding. Equine coat color genetics Before domestication, horses are thought to have had these coat colors.
[1] Equine coat color genetics determine a horse 's coat color. Many colors are possible, but all variations are produced by changes in only a few genes. Bay is the most common color of horse, [2] followed by black and chestnut.

For a gray sire or dam, you must enter what color the horse was before it went gray as well as check the box labeled gray to the right of your color selection.

Understanding how colors are inherited can help breeders make informed decisions about mating pairs and predict foal colors with surprising accuracy. Horse Color Genetics It is easy to understand horse color genetics at a basic level, since the basic coat colors of black, bay, brown and chestnut (including sorrel) are controlled by relatively few genes and not radically affected by the environment.
