Are People Really Born Straight or Gay?

^The gene u mentioned is on speculation, though it is indeed observed that gay men tend to pass on gay characteristics to their children. But since its on speculation, the link has not been established! though the speculated gene has some role in development of parts of brain which is responsible for sexual attraction.

I think it's more on how they are influenced in the early years of childhood. Maybe. Honestly, I never gave these kinds of topics any thought. So this'll be interesting to read.
