In horses, there are two main classes of spotting patterns. One is the Leopard complex, created by the Lp gene, characterized by small spots, seen in breeds such as the Appaloosa and the Knabstrupper. The other group is Pinto, also known as piebald, skewbald, tricoloured, blagdon, and calico in various English-speaking nations. The Pinto group consists of at least four genetically distinct patterns: 1) Tobiano, a dominant gene (TO); 2) Frame overo, an incomplete dominant that create spotting when heterozygous, but is lethal when homozygous, (O); 3) Splashed white, which has yet to be genetically mapped, and may be created by more than one genetic mechanism; and 4) Sabino, which is also created by more than one genetic mechanism, with one form, SB-1 mapped, but SB-1 does not encompass all sabino horses.
