Is homosexuality genetic

Homosexuality is viewed by many as a social problem. As such, there has been keen interest in elucidating the origins of homosexuality among many scholars, from anthropologists to zoologists, psychologists to theologians. Research has shown that those who believe sexual orientation is inborn are more likely to have tolerant attitudes toward gay men and lesbians, whereas those who believe it is a choice have less tolerant attitudes. The current qualitative study used in-depth, open-ended telephone interviews with 42 White and 44 Black Americans to gain insight into the public's beliefs about the possible genetic origins of homosexuality.

Massive Study Finds No Single Genetic Cause of Same-Sex Sexual Behavior

No ‘gay gene’: Massive study homes in on genetic basis of human sexuality

How do genes influence our sexuality? The question has long been fraught with controversy. An ambitious new study — the largest ever to analyze the genetics of same-sex sexual behavior — found that genetics does play a role, responsible for perhaps a third of the influence on whether someone has same-sex sex. The study of nearly half a million people, funded by the National Institutes of Health and other agencies, found differences in the genetic details of same-sex behavior in men and women. The research also suggests the genetics of same-sex sexual behavior shares some correlation with genes involved in some mental health issues and personality traits — although the authors said that overlap could simply reflect the stress of enduring societal prejudice.

There is no ‘gay gene.’ There is no ‘straight gene.’ Sexuality is just complex, study confirms

Few aspects of human biology are as complex—or politically fraught—as sexual orientation. Now, a new study claims to dispel the notion that a single gene or handful of genes make a person prone to same-sex behavior. The analysis, which examined the genomes of nearly half a million men and women, found that although genetics are certainly involved in who people choose to have sex with, there are no specific genetic predictors. Yet some researchers question whether the analysis, which looked at genes associated with sexual activity rather than attraction, can draw any real conclusions about sexual orientation. The handful of genetic studies conducted in the past few decades have looked at only a few hundred individuals at most—and almost exclusively men.

Sexuality cannot be pinned down by biology, psychology or life experiences, this study and others show, because human sexual attraction is decided by all these factors. The study shows that genes play a small and limited role in determining sexuality.
