the rising importance of knowing your horse's genotype, many people have
been hearing the term "agouti."
aa = no agouti
If your horse is "a" (actually shorthand for "aa") then he/she is homozygous recessive for the agouti, but it is easier to understand if I explain it as "NO agouti" (which is technically incorrect, but the easier to picture). Black horses are "aa."
Aa = heterozygous agouti
If a horse is "Aa", then he/she is heterozygous for the agouti and can throw horses with or without the agouti.
AA = homozygous agouti
If a horse is "A" (shorthand for "AA"), the he/she is homozygous for the agouti and will NEVER throw black based horses without the agouti...that means NO blacks, smokey blacks, classic champagnes, blue roans, etc...any black-based foal will have the black limited to the points. So if you have a black mare and you want a foal who is "any color except black", then breed your mare to a stud who is homozygous for the agouti!
