I have a couple 100% het BP. There is possible hets such as 66% and 50% as well but with 100% hets, there is no "possible" mixed in with it. Is 100% hets a guarantee? I am getting a pair of 100% het clowns and I am wondering if there is a possible chance that one or both of them will not prove out or if I am guaranteed to produce at least one clown out of a clutch?
