When two horses are bred together, the appearance of their offspring is determined by a genetics system.
Every horse has both dominant and recessive genes for their color, dilution and pattern. The dominant gene is the one that determines their own appearance, however they have a chance of passing on either of these genes when they breed.
Examining a horse’s pedigree can offer you insights into what genes they have and what they may pass onto their offspring.
Unlike a horse’s color, dilution and patterns, the horse’s parents do not determine what markings may appear on a horse’s head and legs.
