So what makes a palomino actually a dunalino? I am buying a filly that is being called a dunalino but she looks like a plain old palomino to me. I am fine with her being a palomino or whatever she is. She has gone through quite a few colors so I don't really know. Her sire was a dunskin and dam was a black and white if that makes any difference.
Dunalino is a chestnut horse with both cream and dun genes.
Chestnut + cream = palomino
Chestnut + dun = Red dun
Chestnut + cream + dun = Dun palomino or "dunalino"
Some dunalinos don't have very distinct dun factor markings and can be hard to verify without genetic testing (unless you happen to know that the horse had a parent that was tested homozygous for dun)
So, the horse you're looking at might be dunalino with light dun markings, or the sellers might have incorrectly assumed she inherited from her sire and she is actually a palomino.
thank you! That was very helpful. I guess I will just have to wait until I get her to determine for myself what she is. Also do you happen to know if you can change the color on its papers after its already been registered as something else?
