So Im looking at my new horse's registration stuff, and her dad's side (she half paint, half arab) his grandfather is a Thoroughbred.
My question is...I know Appendix is that combination of QH/TB genes, but why on his paperwork is his mother not classified as an Appendix??? She's just credited as a a quarter horse.
Also, how many generations of breeding an appendix with quarter horses before the prodegy is classified as pure quarter horse again? If my horse's great grandfather is a TB, shouldn't she accurately be a arab/paint/QH/TB combo? LOL. I don't know if Im making any sense.
Can someone explain?
