"A team of international researchers has completed a study that suggests we will probably never find a gay gene.' Sexual orientation is not about genetics, say the researchers, it's about epigenetics. This is the process where DNA expression is influenced by any number of external factors in the environment. And in the case of homosexuality, the researchers argue, the environment is the womb itself.
The Epigenetic Key
Writing in The Quarterly Review of Biology, researchers William Rice, a professor at the University of California, Santa Barbara, and Urban Friberg, a professor at Uppsala University in Sweden, believe that homosexuality can be explained by the presence of epi-marks temporary switches that control how our genes are expressed during gestation and after we're born.
Specifically, the researchers discovered sex-specific epi-marks which, unlike most genetic switches, get passed down from father to daughter or mother to son. Most epi-marks don't normally pass between generations and are essentially "erased." Rice and Friberg say this explains why homosexuality appears to run in families, yet has no real genetic underpinning."

Seems the road to homosexuality is agenetic and far more focused after all.The Epigenetic Key
