The system is archaic and you'd think at least ONE registry would bone up on color genetics and get it right.
This is because these sabino or splash horses with the markings you describe have 100% Quarter Horse blood. Gunner is an excellent example of this (Colonels Smoking Gun Quarter Horse
). He's splash overo with a bald face and stockings, but because he is a purebred Quarter Horse, he is registered AQHA.
However, the tobiano gene does not exist in Quarter Horses, and therefore that type of pattern is not accepted into the AQHA. Basically, the AQHA amended their rule so that purebred Quarters can be registered AQHA, no matter their color.
