Tobiano

A tobiano horse can be either “double gened” or “single gened”. The double gened tobiano horses are referred to as homozygous and should produce 100% colored tobiano offspring. All of their foals will have the tobiano gene. On the other hand, a single gened tobiano is heterozygous for the dominant gene. This horse will produce 50% colored tobiano offspring and 50% non-tobiano offspring when bred to non-tobiano mares. Non-tobiano horses are either solid horses or overo colored horses.
