Is it genetically possible?

Arabian Dreams · 04-28-2007, 11:21 PM

Ok, so i have this yearling colt. His sire is a chestnut with 4 high whites, and a blaze, and his dam is TB mare, dark bay, from Seattle Slew lines. My colt has been getting more and more grey in his coat, he is a VERY VERY light roan right now, but, is there any chance that he could grey out? My understandings of genetics is no, there are no greys in his 5 generation pedigree (I think), they are all Chestnuts, bays, and blacks. So, what is the deal? Could he just be roaning a bit? I am going to be very dissapointed if he ends up grey, I love greys, but I love his color better

Well, it sounds like the sire was a sabino carrier, so this could be a manifestation of the sabino gene. It sometimes causes a roany look. Is there white on the tail head? If so, it could be rabicano causing it as well.

Grey is absolutely out of the question, as one parent has to be grey in order to get a grey foal. (Unless there is a fence hopping grey stallion around.... LOL)

Yup definitely sounds like that elusive sabino genetic manifestation

Does your guy have white markings - leg, face? If not, the white hairs are from Rabicano. If he does, they MAY be from the Sabino, but still more likely it's a Rabicano in there.

My colt has 4 high whites and a blaze also, he is a Selle Francais. I have only ever seen Rubicano in one line of QHs. He does have a lot of grey hairs in his mane, but not so much his tail. His tail is more flaxen colored.

Here are some pix

Yes, but does the foal have the whites? If there is any ticking associated with Sabino, it's usually on a fairly obvious expression of Sabino. And since Rabicano often pairs up with Sabino, it's easy for just the Rabicano to express itself, or be passed on while Sabino isn't passed.
