New Research Shows Gay Gene Does Not Exist

Is homosexual natural or a lifestyle choice?

A large scientific study on the biological basis of sexual behavior confirmed that there is no single “gay gene”, but that a complex combination of genetics and environment affects whether a person has same-sex sexual partners.

The research, which analyzed the DNA and sexual experiences of almost half a million people, found that there are thousands of genetic variants related to sexual behavior between people of the same sex, most of them with very small effects.

According to the researchers, five of the genetic markers were “significantly” associated with homosexual behavior, but they are far from even being predictive of a person’s sexual preferences.

“We scan the entire human genome and find a handful – five to be precise – of locations that are clearly associated with a person who reports having sexual behavior with same-sex people,” said Andrea Ganna, a biologist at the Institute of Molecular Medicine at Finland and who co-directed the investigation.

Ganna said that these factors have “a very small effect” and, combined, explain “considerably less than 1% of the variation in sexual behavior with same-sex people who report the same people.”

This means that non-genetic factors, such as the environment, education, personality, parenting, are much more influential in choosing a sexual partner, as with most other human personality, behavior and physical traits, they said. The researchers

The study, the largest of its kind, analyzed survey responses and performed analyzes known as genome-wide association studies (GWAS) on data from more than 470,000 people who had delivered DNA samples and lifestyle information to Biobank of the United Kingdom and the American company 23andMeInc.

When asked why they wanted to conduct the investigation, the team told reporters in a teleconference that previous studies on the matter had mostly been too small to offer strong conclusions.

The results, published in the journal Science on Thursday, found no clear patterns among genetic variants that could be used to significantly predict or identify a person’s sexual behavior, the researchers said.

While supporters of lesbianism says that this findings suggests that being a lesbian or gay is natural, opponents of such lifestyle say that this findings supports what they have been saying all along: that, though there are minor cases (about 1%) of “crash of hormones in human body” – resulting in confusion on one´s sexual preference, but in majority of cases, homosexuality is a choice, and unnatural.

They cite the above scientific study, as confirmation – “environment, education, personality, parenting, are much more influential in choosing a sexual partner, as with most other human personality, behavior and physical traits” – which according to them, is treatable with hormone balancing, just as it´s done, when twins co-joined at birth are separated.
