I have a rescue mare (1/2 paint, 1/2 Shire) due to foal in the next month or so (pasture bred so hard to tell). She's a (fading) black tobiano, to the best everyone could tell on the color chart thread . Anyways, she's here:
She is bred to a chestnut Shire stallion that has a white body spot on the side of his belly:
Now she had a colt at heels when I got her, out of the same stallion. The previous colt has been a fading black in his foal coat, with a white spot on his belly as well, but I believe he is going to shed out in the spring as a bay.
Now I know the chances are most likely this new foal will be just like last years, both in color and pattern, and that's what I am expecting. The solid body color with white socks/facial markings/ some underbody or belly spots is a dominant gene with Shires anyways, and since this year's baby, like last years, will be 3/4 I am not expecting any kind of paint pattern.
But I'm curious to know if there might be something else show up? Is it a certainty the foal will be a bay? Could they produce a chestnut, a black, something else? I know there are formulas to predict different color combos and much of it has to do with prior generations, which I know very little about.
This isn't important or anything. Just want to satisfy my own curiosity. Thanks!
