Equine Genetics 101
Horse colors are built on two base pigments: Red (Chestnut) and Black.
Extension (E): Determines if a horse can show black pigment.
Agouti (A): Pushes black pigment to the “points” (legs/mane) to create a Bay.
Cream (Cr): Dilutes the base color (e.g., Chestnut becomes Palomino).
Homozygous means the horse has two identical copies of a gene and will always pass it on.

Understanding the Odds
Our calculator uses a programmatic Punnett Square. If you haven’t selected “Advanced Markers,” we assume the parents are heterozygous (carrying hidden recessive genes), which is the most common scenario for horses without DNA testing.
Note: These results cover the most common base and dilution genes. Real-world results can vary if horses carry rare genes like Pearl, Dun, or Roan!
