Pearl behaves as a recessive gene with respect to the hair color. One dose of the mutation does not change the coat color of black, bay or chestnut horses. Two doses on a chestnut background produce a pale, uniform apricot color of body hair, mane and tail. Skin coloration is also pale. In Spanish horses, this dilution is known as Pearl. In Quarter Horses and Paints, it has been commonly known as Barlink Factor". Pearl is known to interact with Cream dilution to produce pseudo-double Cream dilute phenotypes including pale skin and blue/green eyes. "
