When two horses are bred together, the appearance of their offspring is determined by a genetic system.
Every horse has both dominant and recessive genes for its 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.
