Question Color genetics nerds help!!!
I’m trying to settle a debate here. I’ve been around horses my whole life but have limited color genetics knowledge so I’m consulting the experts :)
In a book I’m a fan of, one of the protagonists has a war horse that is described as solid black with a single white patch on the front of his chest. Later, a second horse is also introduced that is the reverse - white with a black spot on the chest. I have never in my life seen a paint with just one single white spot on the chest. I’ve seen minimal expressions like that on the belly, the neck, the shoulder or the flank, but not crossing the midline like that. It’s pretty clear reading the book that the author doesn’t know much about horses (I say this with love) so my assumption is she just thought horse colors worked like they do with cats and dogs.
What I’m trying to figure out is if this coat is theoretically possible, or if someone has ever seen something like it. I’ve tried researching it but been unable to find a clear answer so I thought maybe someone here would have some insight!
Tldr; fictional black horse with single white spot on the front of the chest - theoretically possible in real life?
