When the team looked more broadly across all the genomes — across the thousands of genes that they screened for the nearly 500,000 subjects — the genes similarities they found could only account for 8 to 25 percent of same-sex sexual behavior.
“It’s effectively impossible to predict an individual’s sexual behavior from their genome,” said Ben Neale, a geneticist at Massachusetts General Hospital and the Broad Institute who led the study. “Genetics is less than half of this story for sexual behavior.”
I can’t find the study now but I remember another study that found a decently strong genetic component but only for males and only along the maternal line (X chromosome connected like hair loss). And it was correlated with females with a high rate of childbirth so the researches indicated it wasn’t so much a “gay gene” but more likely a “really likes sex with men” gene that expresses in females as sexually activity heterosexuality and in males as sexually active homosexuality. I thought that was really interesting and correlated with several gay male friends of mine that had gay male uncles in their mom’s side.
Female sexuality seems to me more complicated and much more of a sliding Kinsey scale that seems more heavily influenced by social norms, peer behavior, and environmental factors like negative interactions with males. But I don’t have any science for that one — just 50 years of observations!
