 A commercially available DNA based test is likely to be developed in the near future, which breeders can use to determine if LP is present in horses that do not have visible Appaloosa characteristics.Not every Appaloosa exhibits visible coat spotting, but even apparently solid-colored horses that carry at least one dominant LP allele will exhibit characteristics such as vertically striped hooves, white sclera of the eye, and mottled skin around the eyes, lips, and genitalia.Appaloosas may also exhibit sabino or pinto type markings, but because pinto genes may cover-up or obscure Appaloosa patterns, pinto breeding is discouraged by the ApHC, which will deny registration to horses with excessive white markings.
