I want to know if you can have the offspring mate with one of his or her own parents. It's odd, yes, but I'm curious if Bethesda thought this through.
Edit: I'm going to cross breed, by this I mean like this
Parent 1 + Parent 2 Parent 3 + Parent 4 = Child 1 = Child 2 Parent 1 + Child 2 Parent 2 + Child 3 = Child 3 = Child 4
I hope this visual (somewhat) representation will show what I'm planning to do.
