Hi, I'm Tim Wigren, owner and operator of Command Performance here in Ridgefield, Washington. I'm here to talk to you about what is a homozygous pinto? Quite simply a homozygous pinto is a pinto horse who genetically cannot produce anything other than another pinto. With ninety-nine percent accuracy, they've been able to determine that a homozygous stein can produce, ninety-nine percent of the time, homozygous pinto babies or colored babies. A homozygous mare can only produce pinto babies. A horse who is heterozygous can either produce a colored baby or a solid colored baby. The reason a homozygous is so popular is because it very much assures the pinto breeder that they will be getting color.
