Bar geneticists have had only a behaviour of underpowered studies to address a complex, fraught, next often stigmatized square of human habits.

Sexy xXx Base pix Homosexual genetics or choice Clitoris I n a recent Guardian article , Simon Copland argued that it is very unlikely people are born gay or presumably any other sexual orientation. Scientific evidence says otherwise. It points strongly to a biological origin for our sexualities. I would argue that understanding our fundamental biological nature should make us more vigorous in promoting LGB rights. Three gene finding studies showed that gay brothers share genetic markers on the X chromosome; the most recent study also found shared markers on chromosome 8. This latest research overcomes the problems of three prior studies which did not find the same results.
