What you are saying isn't necessarily true, assuming genealogy plays a role in whether someone is gay or not. Recessive genes can express themselves the same way a mother and father that both have brown eyes can have a child with blue eyes.
Say a family has three kids, one is gay and two aren't. Even if the gay child never has kids, there are recessive genes that can be passed on by the siblings to their children. Depending on what recessive genes their partners have, different outcomes can occur. Again, this is of course assuming genealogy plays a role in homo/hetro.
Sure, I buy that completely, but as soon as the recessive gene expresses itself and the person only desires to have same sex relationships, it stops propagating to offspring, at least in this simplistic model.
