Horse Coat Color Simulator Tool


Equine coat color genetics determine a horse's coat color. There are many different coat color possibilities, but all colors are produced by the action of only a few genes. Try pressing the genetic buttons to the left of the horse below and see how they all interact!


*Capital letters indicate DOMINANT variants and lower-case letters indicate RECESSIVE variants. Some of the color variants below are not yet genetically discovered but known to be heritable. More discoveries to come!

**This is a legacy tool designed by Jennifer Hoffman. Not all of the colors/variants shown are fully mapped. For a current demonstration of known/mapped variants only, please see Build-a-Horse.
