+1 on this!! My gelding is as grade as they come. He's a Percheron/paint cross. Not generally something I'd expect to see (except from a PMU farm, maybe). He came out with the best traits of both. The Percheron build and size with the lovely paint markings, and the nice draft horse personality and intelligence. His half-sister (same fugly paint sire) didn't fair so well. She's long-backed, her neck ties in funny and is just weirdly built in general, her legs are a mess, and as a coming-3yo she's about 6" butt high (a solid 15hh at the withers and 16.2hh at the butt). Not only that, she's not the sharpest tool in the shed and she's honestly a bit hot. They came from the same sire (APHA stallion Little Bit of Black) with nearly identical Percheron dams (both big, typy black Percheron mares).
Looking on Google at the Friesian/QH crosses, it looks like it can be a really good match or not so much. My question is this: what if you don't get the good side of the match? What happens if you get all the worst traits/qualities of both in the foal?
