When you put in that a horse is a bay it asks if it is a red carrier. If the horse has a chestnut parent or grandparent, does that make it a red carrier? How can you find out if a horse is a red carrier without an actual genetics test, is there a way to tell from it's parentage?
Same question goes to Agouti.... is there any signs that it is an agouti carrier either in it's coloring or by the coloring in it's parentage?
I just want to understand the whole gentics thing a bit more.
