Explain to me how there can be a genetic component without genes?

It's indeed a complicated issue, which you said yourself. Perhaps your above question should be refined to: Since there is no gay gene, how can homosexuality have a genetic component?

My first post to you, post 61 (which you didn't reply to) provides some information you may find helpful. But if you still don't understand the differences after re-reading post 61, you should research the issue yourself.

The link in Post 61 says that "many think that nature and nurture both play complex roles."

Nature, in this context, means there is a biological predisposition toward homosexuality; and that in turn implies something in the genetic makeup.

You, sir, are simply dancing around the point. It's not clear why.
