Ok, since horse genetics have been introduced by someone else...I know that there are only two "actual" colors in horses, red (chestnut) and black. Everything else is a variation or dilution of those two colors. Am I correct in assuming that it's similar/same in dobes then, that there are Red and Black and everything is based off those two?
Frame overos are like merles. Breed two of them together and you will more than likely end up with a lethal white, and unlike dogs, where the pattern/"lethal" whites are more affected in vision and hearing but usually live to a decent age, lethal white foals usually die within a few hours of birth due to either a blocked intestine or an autoimmune deficiency. Those that don't die immediatly are usually euthanized to minimize any further suffering on the foal's part.
