đ§Ŧ Horse Color Genetics Explained
Base Colors
All horse colors derive from three base colors controlled by Extension (E) and Agouti (A) genes: Black, Bay, and Chestnut.
Dilution Genes
Genes like Cream, Dun, and Champagne lighten the base color, creating colors like Palomino, Buckskin, and Dun.
Modifier Genes
Grey, Roan, and Pinto patterns modify the base color or diluted colors to create the final appearance.
Inheritance Patterns
Some genes are dominant (like Grey), while others require two copies (like Cream for double dilutes).
Lethal White
Homozygous Overo (O/O) results in Lethal White Syndrome. Always test breeding pairs for Frame Overo.
Genetic Testing
Commercial tests are available for most color genes to accurately predict breeding outcomes.
