Henlei/ balck diamond? They look slightly nicer than henlei/leo. I think the reason why Brent's don't look that extremely hybridised, is because the female leo breeds with the male leo, as well as the male Henlei.
This is what i think happened with T1's adult male P14/Pearl. The mother of his adult male P14/Pearl bred with the male P14 as well as the male pearl. This is why T1's male looked so much like a pure blood and not a hybrid. Unfortunately the pearl blood was passed through to my male pup from his breeding pair, and now you can see the pearl side of his adult male.
Don't know if this makes any sense, please tell me if it doesn't and i will re-phrase it.
