Justin makes a very good point in that the behavior is all part of the egg development process. By the time the shell has formed around the embryo the deal is done genetically speaking. Even with artificial insemination you would still need a visually proven homozygous animal for all recessive traits to get 100% hets for every trait otherwise the offspring would be 50% poss hets for about 8 -10 different traits.

LOL I would be neat to do with say a co-dom animal that is a one of a kind and maybe dies to have its genetic material on hand to reproduce the trait artificially. But thats the only reason I could see doing it.
