The main reason incest is criminalized is because children from incestuous unions are more likely to be deformed, mentally retarded, and generally undesirable.

I beg to differ. The main reason against incest and rather obvious is the detriment to the child being sexually abused or used by the adult parent. I'm not aware of any cultures outside dog cultures that endorse parent/child incest.

Ain't that the truth. Does the AKC recognize them when they're bred that close?

But what if the daughter is over 18? Consenting adult, right? What if your adult daughter wanted to hook up with your 40 year old brother? No problem, right?
