 This is generally noticed when a tobiano horse has spots with roaning around the edges, or other sabino traits such as belly white, white on the chin, or "high white" markings.Tobiano is a dominant gene, is not related to sabino, but because pintos with different spotting patterns are often crossed on one another, it is easily possible for a horse to carry multiple spotting pattern genes.Tobiano-sabino blends registered with color breed associations for spotted horses may be categorized as "tovero".
