I . the Color Gene C
THE ABC OF COLOR INHERITANCE IN HORSES W. E. CASTLE Division of Genetics, University of California, Berkeley, California Received October, 27, 1947 HE study of color inheritance in horses was begun in the early days of Tgenetics. Indeed many facts concerning it had already been established earlier, by DARWINin his book on “Variation of Animals and Plants under Domestication.” At irregular inteivals since then, new attempts have been made to collect and classify in terms of genetic factors the records contained in stud books concerning the colors of colts in relation to the colors of their sires and dams. A full bibliography is given by CREWand BuCHANAN-SMITH (19301. By such studies, we have acquired very full information as to what color a colt may be expected to have, when the color of its parents and grandparents is known. This knowledge is empirical rather than experimental in nature. For horses being slow breeding and expensive are rarely available for direct experi- mental study, such as can be made with the small laboratory mammals, mice, rats, rabbits and guinea pigs. We have definite information that color inheritance in horses involves the existence of mutant genes similar to those demonstrated by experimental studies to be involved in color inheritance of other mammals. But the horse genes have been given special names, as they were successively discovered, and it is difficult at present to correlate them with the better known names and geneic symbols used by the experimental breeders. The present paper is an attempt to make such a correlation. Just as in morphological studies comparative anatomy was found useful and still is used to establish homologies between systems of organs, so in mammalian genetics, a comparative study of gene action in the production of coat colors and color patterns may also be of value. -

Meiner Meinung nach sollte jeder Züchter über bestimmte Grundkenntnisse der Farbvererbung verfügen, da einige Farbschläge auch gesundheitliche Risiken für das Pferd bergen. Eine besondere oder seltene Farbe ist sicher ansprechend und erhöht den Wert eines Pferdes, dennoch sollte stets die Gesundheit und die Qualität des Pferdes im Vordergrund stehen. Zunächst werde ich einige genetische Grundlagen erläutern, damit die verschiedenen Erbgänge der Farb-Gene verständlich sind. Erst danach werden die drei möglichen Basisfarben und dann deren Aufhellungen und Muster, sowie die fortschreitende Depigmentierung aufgeführt. 1.2 Genetische Grundlagen Die Erbanlage für die Fellfarbe liegt beim Pferd in den Chromosomen, die, wie beim Menschen, immer paarweise vorliegen. -

Genetic Screening Tests available Symbol Name Description of variant effects Genetic Disease Testing CA is a neurological disorder that affects the cells in the cerebellum, causing head tremors, ataxia and other effects. Affected horses are more likely to fall and are generally not safe to ride. Symptoms appear from 6 weeks to around 4 months old. CA has been linked to a mutation in the TOE1 Cerebellar CA gene and is a recessive disorder, meaning that a horse must Abiotrophy be homozygous (CA/CA) to be affected. If a horse is a carrier (CA/n), it will not show any clinical signs of CA, but it will pass the variant on to approximately half its offspring. Mating to other carriers should be avoided to prevent the birth of an affected foal. LFS causes neurological dysfunction in foals. The symptoms include seizures, hyperextension of the limbs, neck and back, leg paddling, and inability to stand. As the name suggests, LFS also dilutes to the coat to a pale lavender pink or silver colour. The foal will not improve and will die, so it should be euthanised. LFS is a recessive disorder so two copies of the Lavender Foal defective version of the MYO5A gene must be inherited LFS Syndrome (LFS/LFS) for a foal to be affected. If a horse is a carrier (LFS/n), it will not show any clinical signs of LFS. However, there is a 50% chance it will pass the variant to its offspring, so mating to other carriers should be avoided to prevent the birth of an affected foal. -

Color Coat Genetics
Color CAMERoatICAN ≤UARTER Genet HORSE ics Sorrel Chestnut Bay Brown Black Palomino Buckskin Cremello Perlino Red Dun Dun Grullo Red Roan Bay Roan Blue Roan Gray SORREL WHAT ARE THE COLOR GENETICS OF A SORREL? Like CHESTNUT, a SORREL carries TWO copies of the RED gene only (or rather, non-BLACK) meaning it allows for the color RED only. SORREL possesses no other color genes, including BLACK, regardless of parentage. It is completely recessive to all other coat colors. When breeding with a SORREL, any color other than SORREL will come exclusively from the other parent. A SORREL or CHESTNUT bred to a SORREL or CHESTNUT will yield SORREL or CHESTNUT 100 percent of the time. SORREL and CHESTNUT are the most common colors in American Quarter Horses. WHAT DOES A SORREL LOOK LIKE? The most common appearance of SORREL is a red body with a red mane and tail with no black points. But the SORREL can have variations of both body color and mane and tail color, both areas having a base of red. The mature body may be a bright red, deep red, or a darker red appearing almost as CHESTNUT, and any variation in between. The mane and tail are usually the same color as the body but may be blonde or flaxen. In fact, a light SORREL with a blonde or flaxen mane and tail may closely resemble (and is often confused with) a PALOMINO, and if a dorsal stripe is present (which a SORREL may have), it may be confused with a RED DUN. -

EQUINE COAT COLORS AND GENETICS By Erika Eckstrom Crème Genetics The cream gene is an incomplete dominant. Horse shows a diluted body color to pinkish-red, yellow-red, yellow or mouse gray. The crème gene works in an additive effect, making a horse carrying two copies of the gene more diluted towards a crème color than a horse with one copy of the gene. Crème genes dilute red coloration more easily than black.
