Gay and lesbian and genes

Last updated November 10, at pm. This is often used by those who would argue against the biological nature of same sex attraction, by treating biological factors as immutable, a fixed point in human development. The science suggests that this is not the case. Jenny Graves, professor of genetics at LaTrobe University in Melbourne, has no problem with the concept of gay genes. There are probably many genes that affect human sexual orientation.

Biology and sexual orientation - Wikipedia

There has been much debate about what causes homosexuality. People often wonder if there's a gay gene or if homosexuality is caused by environmental factors, such as upbringing, child molestation, an absent mother, or an affectionate father. Although there have been few studies on the cause of homosexuality, the debate seems to be divided, with scientists in one corner and religious fundamentalists in another. The APA goes on to say that sexual behavior is not the same as sexual orientation. Certainly, gay individuals can engage in heterosexual sex.

An evolutionary view of the ‘gay gene’

W hat are the Darwinian underpinnings of same-sex attraction? And why do same-sex relations persist, generation after generation, if these individuals are less prone to procreate? A massive genetic study aims to unravel these basic biological questions.

Two gene variants have been found to be more common in gay men, adding to mounting evidence that sexual orientation is at least partly biologically determined. How does this change what we already knew? We have known for decades that sexual orientation is partly heritable in men, thanks to studies of families in which some people are straight and some people are gay. Both findings were confirmed in a study of gay and straight brothers in For the first time, individual genes have been identified that may influence how sexual orientation develops in boys and men, both in the womb and during life.

Ich entschuldige mich, aber meiner Meinung nach irren Sie sich. Ich biete es an, zu besprechen. Schreiben Sie mir in PM.

Es ist schade, dass ich mich jetzt nicht aussprechen kann - ist erzwungen, wegzugehen. Aber ich werde befreit werden - unbedingt werde ich schreiben dass ich denke.
