Rabicano
From Wikipedia, the free encyclopedia
Rabicano is a horse coat color that appears to be a type of partial roaning. Horses with the rabicano pattern usually have white hairs intermingled with the base coat color in limited areas, not the entire body. This roan-like effect that is caused by a genetic modifier that creates a mealy, splotchy, or roaning pattern, usually limited to the belly, flanks, legs, or tailhead areas, or any combination thereof.
Unlike a true roan, most of the horse's body will not have white hairs intermingled with solid ones, nor are the legs or head significantly darker than the rest of the horse.
Rabicano is thought to be a dominant gene, according to the equine geneticist Sponenberg. See Equine coat color genetics.
