I don't see why not. But color should be the icing on the cake, not the focus. But a dun mare has the gene to throw to a foal. But this is more of a color and genetics question. Play around with color calculators and see what you will get by combining different horse colors together. Posted via Mobile Device
Depends on several factors as to the chance but if the mare is Htro for Dun and the stallion does not carrie it then you have a 50% chance of getting a dun foal. However even at that you may or may not get one.
