My filly is 100% quarter horse, why is she getting white spots on her rump?

My 1 year old quarter horse filly is getting unusual spots on the top of her rump. I know she isn't going to be gray, she doesn't have any gray around her eyes. She's a rich sorrel color, with light (not flaxen) mane, and a black, red, blonde, deep red (almost purple) tail.. ..


the spots range in size from a dime to a nickel... and some look more like short streaks.





ANY HELP APPRECIATED, IM CONFUSED!!





THANK YOU!

Im not sure what country you are in, but in australia if i breed an appaloosa with a QH the foal would be called a first cross QH , if I then breed that foal back to a QH it would be known as a second cross QH. If you then breed that second cross horse back to a QH, the foal it had whould be able to be registered as a pure bred QH, so it is possible 3 genirations back you may have some appaloosa breeding. hope you understood that!

Looking at the photo,I still think that she may be a silver dapple.as she resembles the horses in the links I posted. I guess that only time will tell. She's a real cutie,though.
Reply:It is not unusual for QH's to have white spots on them somewhere. Afterall, this is where the paint breed came from. The "spots" could also be an expression of a gene that basically causes a slight roaning. It is not a true roan gene, but does result in similar markings. As for the spiral curls in the tail, this is because she is still a baby. As she grows and matures, her tail will straighten.





In the US, a horse with any breeding other than QH or TB cannot be registered with AQHA. I don't know about rules for other countries, but if the horse is AQHA registered regardless of where it is, it cannot have appaloosa breeding.
