(EDNRB) gene is associated with the frame overo pattern produces Lethal white syndrome if homozygous, but carriers can be identified with a DNA test. Prevalence The cream gene is found in many breeds. It is common in American breeds including the American Quarter Horse, Morgan, American Saddlebred, Tennessee Walking Horse, and Missouri Fox Trotter. It is also seen in the Miniature horse, Akhal-Teke, Icelandic horse, Connemara pony, and Welsh pony. It is even found in certain lines of Thoroughbreds, warmbloods, and the Lusitano. The Andalusian horse has conflicting standards, with the cream gene being recognized by some registries, but not explicitly mentioned by others. The cream gene is completely absent from the Arabian horse gene pool, and is also not found in breeds with stringent color requirements, such as the Friesian horse. Cream mimics Other coat colors may mimic the appearance of a cream coat color. The presence or absence of the cream gene can always be verified by the use of a DNA test. Also, as explained in "Mixed dilutes" below, horses may simultaneously carry more than one dilution gene. Dilution genes which, by themselves, may be confused with cream dilutions include the following: Bay dun vs. buckskin: the action of the dun gene on bay produces a buckskin-like coat. Additional confusion occurs because in some countries, it is still customary to refer to buckskins as "dun", particularly in the British pony breeds. Bay duns tend to have a flatter coat color, more tan or peanut butter-colored than bronze, and also exhibit primitive markings. Amber champagne vs. buckskin: the action of the Champagne gene on bay can also produce a buckskin-like coat. Champagnes can be identified by their freckled skin, hazel eyes, and chocolate (rather than black) points. Flaxen chestnut vs. palomino: Horses having light chestnut coats with flaxen manes and tails, such as those found in the Haflinger breed, can be confused with palominos. However, unlike chestnuts, palomino is inherently a heterozygous condition and thus cannot be true-breeding. Furthermore, even the lightest chestnut will retain "red" character in the hair, rather than gold. Gold champagne vs. palomino: the action of the Champagne gene on chestnut was for many years called pumpkin-skinned palomino. However, lighter, freckled skin and hazel eyes identify a gold champagne, which can otherwise look much like a palomino. Pearl vs. palomino: the action of the pearl gene only occurs when the pearl allele is homozygous.
