Volunteers from over families responded. Researchers asked them questions about their sexuality, the size and structure of their families, and took DNA samples. The region also goes by another name: GAY-1, a genetic marker linked to male homosexuality. Conservative attitudes remain unchanged, however.

What do the new ‘gay genes’ tell us about sexual orientation? | New Scientist

The reasons behind why people are gay, straight or bisexual have long been a source of public fascination. Indeed, research on the topic of sexual orientation offers a powerful window into understanding human sexuality. Among the indigenous Zapotec people in southern Mexico, individuals who are biologically male and sexually attracted to men are known as muxes. They are recognized as a third gender: Muxe nguiiu tend to be masculine in their appearance and behavior; muxe gunaa are feminine. In Western cultures, they would be considered gay men and transgender women, respectively. Several correlates of male androphilia—sexual attraction of biological males to men—have been shown across different cultures, which is suggestive of a common biological foundation among them. For example, the fraternal birth order effect—the phenomenon whereby male androphilia is predicted by having a higher number of biological older brothers—is evident in both Western and Samoan cultures.

Largest study of gay brothers homes in on 'gay genes'

Log in Advanced Search. Genetics plays a role in male sexual orientation but social and environmental factors are also involved, research suggests. Scientists tested the DNA of pairs of homosexual twins, making this the largest study of its kind. They found that homosexual men shared genetic markers in a region of chromosome 8, and the Xq28 region of the X chromosome. The findings were originally presented by Professor Michael Bailey at the annual meeting of the American Society of Human Genetics two years ago.

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.
