Not every condition is a product of either genetics or choice. Poll needs a none-of-the-above choice.
Genetics implies heredity. So far as I know, there is absolutely no evidence to suggest that is the case for pedophilia. It would be abnormal. (I have read that gay men are correlated with very fertile mothers though.) Attraction is not a choice either. [sub]In a deterministic world, choice is just an illusion anyways.

Now lets bring in the other factor: environment. How you're raised, what you've been exposed to, in combination with your genetics (which governs to some extent how your body responds to the environment) will determine your mental conditioning. You are the product of your genes and your upbringing.
That's really all there is to it. It's not raw genetics until demonstrably proven otherwise, because we see no correlation between relatives of pedophiles and tendency to be a pedophile. Its certainly not a choice, either.
If you make a poll, you should allow an alternative viewpoint option, unless your goal is to pigeonhole those who disagree into a listed option. ("Delicious flat chest" does not count.)
