Not my foal. Saw this on another forum... Sire is cremello. Dam is sorrel gone grey. Baby looks chestnut as the day is long... http://www.horseforum.com/horse-colors-genetics/will-he-change-colors-i… Ideas?? Just really dark pali from the grey maybe?? (First foal pic is the dam before greying, foal is after you scroll down).

Maybe it's one of those freak mutations where the gene is restored to wild type? Rats can spontaneously revert from albino back to non-albino. Supposedly, from this handbook we have rom Charles River.

Not that this has anything to do with that horse, but I didn't know what you were talking about so I just looked that up and that's really, really interesting... just thought I'd share that :grin:

It is weirdly interesting to me, too. I wonder if that can happen in horses - the cream gene being repaired?

I bet the foal is a dark, dark palomino. After browsing I've seen a couple that LOOK chestnut, but SHOULD be palomino and eventually are tested to be so. Just another way horses can try to throw us off their trail.

Do you have a pedigree or any pixs of the sire?

Not saying he isn't what he is proported to be, but I ran across a horse last month that I would have swore was a cremello but turned out to be a splash white, max sabino (splash gave her the blue eyes). I was so sure until I looked at her pedigree (parents chestnut QH-based Paints) and there wasn't a cream within 3 generations...she sure was pretty, but alas was NOT cremello, and as such, would not produce cream babies.

Oops, okay found the sire..definitely cremello...ee/AA so that rules that out. The foal has to be either a dark pali going grey or somebody messed up somewhere.

The reversion to wild type can happen rather frequntyly in merle dogs according to the researchers who isolated the mutation but I've never heard of it happening in horses. Would be interesting to see.

If he is pali going gray it makes sense that he would be born darker like all gray babies. Just more dramatic since he's a dilute. Champagne gray babies do the exact same thing.

Gosh that's really chestnut looking!! I'd assume it will eventually look more pally, and as others have said the grey might be helping the foal looking darker

An update on this one. The OP was banned over on the Horse Forum, the general feeling was that she was making up tales about non existent horses. Someone also pointed out that the pic of the dam as a foal doesn't match the pic of the dam as an adult - the white marking that was present as a foal left no pink skin on the muzzle of the adult horse.

All in all, this looks like a fabricated tale and so we were right to have boggling minds :BH

Oh man, I don't feel looney anymore... lol

I mean, it was plausible since being grey most likely, born very dark but most of the palominos who look chestnut still have a slight gold sheen to him. He looked red as red could be...

Genetics, why you do this to me?? lol
