![]() In addition to a white pattern, the expression of leopard complex includes several components: mottled skin around the muzzle, anus, genitalia, and eyes, stripped hooves, easily visible sclera (white of the eye) and progressive roaning, or loss of pigment, in the pigmented areas of the coat with age. Leopard complex is also found at a lower frequency in the American Miniature Horse and Spanish Mustang breeds. Other breeds around the world that exhibit this pattern include the British Spotted Pony, Knabstrupper, Noriker, and Tannu Tuva Pony. Matings with any genotype are predicted to produce foals with leopard complex spotting.Įxpression of Leopard Complex is variable and white patterning may not be present in all horses that inherit the LP allele, but those with LP will progressively lose pigment as they age.Ī popular source of symmetric white patterning called leopard complex spotting (LP), also known as Appaloosa spotting, is characteristic of the Appaloosa and Pony of the Americas breeds. They will transmit a leopard complex spotting variant to all of their offspring. Horses with this genotype will also have congenital stationary night blindness (CSNB) and are at elevated risk for equine recurrent uveitis (ERU). The size of the pattern is dependent on the modifiers present.
