Understanding Horse Color Genetics

Horse coat color is determined by genes inherited from both parents.

1. Base Colors

  • Extension (E): EE/Ee = Black base, ee = Red
  • Agouti (A): AA/Aa + E = Bay, aa + E = Black

2. Dilution Genes

  • Cream: Single = Palomino/Buckskin, Double = Cremello/Perlino
  • Dun: Adds dorsal stripe and primitive markings
  • Silver: Dilutes black pigment to chocolate
  • Champagne: Creates metallic sheen

3. Gray Gene

Dominant gene causing progressive whitening with age.
