 Because the occasional individual is born with little or no visible spotting pattern, the ApHC allows "regular" registration of horses with mottled skin plus at least one of the other core characteristics.Horses with two ApHC parents but no "identifiable Appaloosa characteristics" are registered as "non-characteristic," a limited special registration status.There is a wide range of body types in the Appaloosa, in part because the leopard complex characteristics are its primary identifying factors, and also because several different horse breeds influenced its development.
