What is brown horse color?

Brown horses have a dark brown or dark seal color to their coat and black points on their lower legs, mane, and tail. They have a reddish tan or lighter brown areas around their muzzles, eyes, behind their elbows, and in front of their stifle.

What is the genotype of a brown horse?

geneticists, including the senior author, have used the term brown to designate only the genotype which is homozygous for the recessive b allele of the gene for black pigment, B. In horses, this would restrict the term to genotypes of chestnut and sorrel, and their subordinate classes, such as palo- mino and cremello.

Is agouti a breed or color?

As you may notice, wild rabbits appear chestnut agouti. Different rabbit breeds call this color by many different names (Chestnut, chestnut agouti, sandy, copper, brown, castor) and it looks very different on different fur types.

Can a black horse have agouti?

The agouti (allele A) is a modifier that regulates the distribution of black pigment. Put simply, it limits the black on a black horse to the points (ears, legs, mane, and tail). A red based horse (see “color recipes”) can carry the agouti without showing it, as the agouti does not affect red pigment.

Testing bay horses might be desired to see whether the horse carries one (Aa) or two (AA) copies of the Agouti allele. A homozygous Agouti (AA) horse will always pass Agouti to its offspring whereas a heterozygous (Aa) horse will have a 50% chance of passing on the gene.

How does the agouti gene affect breeders?

Quick Summary. The agouti gene controls the distribution of black pigment, and determines whether a horse will have a bay or black base coat color. Phenotype: The agouti gene controls the distribution of black pigment, and determines whether a horse will have a bay or black base coat color.
