(PS: This is a metaphorical question. Both horses, the stallion and the mare do exist, but there are no plans to breed to two. Its purely metaphorical, because I was wondering about genetics and stuff so... yeah.)
Can anyone think of any two horses that if you bred them together, you would 100% know what color your foal would be? Aside from like Freisians and stuff, that are only one color throughout the whole breed. I'm just really curious.
