Dominant white is a group of genetically related coat color conditions in the horse, best known for producing an all-white coat, but also for producing some forms of white spotting and white markings. Dominant white horses are born with unpigmented pink skin and white hair with dark eyes, although the amount of white hair can vary. Dominant white is a rare condition, and under normal conditions at least one parent must be dominant white to produce dominant white offspring. However, there are documented cases where dominant white has occurred as a spontaneous mutation.
