John's smile grows as he nods patiently. "Yeah--I've always kinda seen sixty-forty odds of it. More likely than not that, if you breed two horses, the babies take after their parents in fun and interesting ways when it comes to their personality. Like Co's parents--one of 'em has a thing for stealing shit. Co doesn't do it often, but it is in her. You put a real friendly stallion with a mare who loves to eat, and you might get a baby who likes to share food. Or something totally different--maybe a little snack thief. But if you put two horses together that you know, you can be pretty sure of the type of horse you'll get."
