It would be like the blue eye gene, more common than brown among Nothern Europeans but virtually non-existent among some groups.
It's inborn and not changeable certainly, but I don't think it's genetic.
The problem with this hypothesis is that eye-color is regulated by a single gene, whereas behaviors with genetic components can have many genes each inputting into the behavior. The different genes may each have different proportions in different populations, but still result in gayness.
If it's inborn, genes are regulating it.
