True. Genetic mutation/problems/diseases do pop up. Let's take something similar -- alcoholism. It is also questioned as to having a genetic component along with an environmental cause. Plus, you can do your same identical/fraternal twin studies.
If alcoholics did not breed, therefore, there would be even less occurrences than there are now. So, eliminating the possible genetic component completely will not stop the mutation, only reduce the occurrence.
Alcoholism, like homosexuality or pedophilia, may be "genetic" in the sense that a person, randomly, may be predisposed to that behavior. That doesn't mean that you have to drink -- one can decide to quit.

Dad liked to drink vs. friends like to drink. Ok.

I gotta read up on that stuff - got any twin disease study links?

I think this is a bad example for you - alcohol actually encourages breeding in both males and females. I am still waiting for a class action lawsuit by unwed mothers against the makers of both Boone's Farm and MD20/20 for unwanted pregnancies. But I digress.

True. But one can't decide to either be a siamese twin or not.
In my defense, these are big huge issues that I don't completely understand from either a religious or scientific point of view - but I don't think anyone else does either.
