The Pearl gene is also known as the "Barlink factor". It resembles the champagne and cream genes but is neither. It is an incomplete recessive gene, with one copy doing nothing to the coat while two copies will mimic champagne. When one copy of pearl and one copy of cream is present a pseudo double dilute is the result. Many breeders theorize that pearl and cream are located at the same locus. Meaning that a horse with both cream and pearl will only pass one or the other but not both to its offspring. Pearl has been located by UC Davis and they offer a test but they have not published their findings so we cannot at this time know for certain if this theory is correct.
