簡介 As researchers in biology and sociology who are also gay men, we have long wondered (and debated) whether sexual orientation has any biological basis.

study published Thursday in Science looked at the DNA and sexual behavior of nearly 500,000 people… Researchers since the 1940s have described sexual orientation as a single trait that exists on a scale, ranging from “exclusively heterosexual” to “exclusively homosexual.” But the new study suggests that sexuality is more diverse than that — many different things, rather than one thing in greater or lesser degrees.

But when the researchers tried to add up the contributions of each DNA variant they examined, they could predict less than 1 percent of the variation among study participants.

簡介 The findings of a study of the genetic basis of homosexuality published last week in the journal Science explode the false narrative that being gay is an innate condition that is controlled or largely compelled by one’s genetic makeup.

Rebutting decades of search by LGBT scientists for a “gay gene”, the study’s first author flatly concludes “it will be basically impossible to predict one’s sexual activity or orientation just from genetics”.
