I don't know a thing about breeding, but does breeding a mare to a stallion who 'corrects' her conformational faults actually give you a foal that's an improvement on the mare? I've read that before, but my rough comprehension of genetics and inheritence suggests that it's a total crapshoot. Like if I'd wanted to breed my very long-backed, loose-coupled mare, I would have chosen a short-coupled stallion with a strong back. As I understand it, my foal might inherit his dam's long back. He might inherit his sire's short back. He might end up somewhere in between. Who knows? It's not a guaranteed way to get a horse that improves my horse's conformational shortcomings. Obviously you want to hedge your bets and not breed something that has the same or similar faults as your mare, but you might get them anyway.
Is that correct?
Absolutely- breeding is a genetic lottery so you might choose a stallion that has strengths in areas of your mares weaknesses and get lucky with improving them, or not. You have to be willing to get the same as the mare but improve your odds as much as you can by choosing a stallion with a strong genetic history of producing the types you want- himself through his progeny and/or through his own sire and dam.
For example, I chose a couple of typey stallions for my long backed mare who had a short, awkward neck but was a great athlete with a huge heart. Her first foal mostly had the same weaknesses as her so I chose even more carefully the second time and her second foal has taken a lot from his sire and is strong where his mother was weak- the stallion has improved on her in every way.
It's not enough just to pick a stallion you like the look of if you need to improve, it needs to really stamp its offspring with the qualities you need.
BTW, when I asked this forum many years ago what stallion to use on my mare most people who commented were horrified I would breed from her. There's no way on this planet I could have got anything more perfect for me than my 5yr old, but I've also had the heartbreak of losing her first foal.
