  • Researchers believe that there are many other factors that might affect gender or same-sex attraction such as social and environmental influences
  • They have also disapproved previous assumption about the existence of single ‘gay genes’ in homosexuals

A new major study argued about the existence of single “gay genes” among homosexuals.

It emphasizes not only relying on a single gene but many. Researchers have also mentioned other factors that possibly affect drive for same-gender attraction other than analyzing complex genetic data.

“Across human societies and in both sexes, some 2% to 10% of individuals report engaging in sex with same-sex partners, either exclusively or in addition to sex with opposite-sex partners,” wrote the authors in their study.

Researchers have conducted analysis among nearly half a million participants which was funded by the National Institutes of Health and other agencies.

After analyzing the data from the participants, they found differences in the genetic details among homosexuals.

Instead, a person’s attraction to someone with the same gender must come from the complex combination of genetic and environmental influences, which is also similar to most of the human traits.

“I hope that the science can be used to educate people a little bit more about how natural and normal same-sex behavior is,” said Benjamin Neale, a geneticist at the Broad Institute of M.I.T. and Harvard and one of the lead researchers on the international team.

“It’s written into our genes and it’s part of our environment. This is part of our species and it’s part of who we are,” he added.
