I'm not sure how I feel about the whole cloning situation, but I know even in the horse world there are quite a few on the ground. My thing with that is, they state that there can be differences in height and slight variations in bone density/structure. If they clone a gelding and offer the clone for stud, I still feel like it should be proven as well regardless of what the original did. What if it is not as fast? What if the gelding, had he been a stud, wouldn't throw a decent foal in the first place? There are always gambles in breeding, but I feel just because an animal is a genetic copy doesn't mean it should be assumed that it is just as good. Then if you throw in personality, it is not the same animal, it won't think or act exactly the same. What if the stud was just a monster? Not saying all studs are, I've met plenty of nice ones, but breeding to something with godawful personality just because it took millions to make him? Their are plenty of sour studs out there bred for just their pedigree, so eliminating it wouldn't get rid of that entirely.
At one point weren't foals conceived by AI unregisterable? Or was it just with frozen semen of stallions deceased? Not necessarily AQHA, but somewhere out there. Maybe in the future it might be more acceptable, but for now I think it will be a gray area.
