That amounts to an evolutionary paradox: gay men have fewer children, so one would expect that the trait would disappear over time. Now a team of researchers has carried out the largest-ever genetic study of sexual orientation Gay Cambridge connections found evidence consistent with one possible explanation.
Details of the unpublished study have been described in a public research plan, in two scientific abstracts, and by Lebanese free sex in United Kingdom at a scientific meeting held in June at the Broad Institute, a genome research center in Cambridge, Massachusetts. The hunt for sexual orientation genes—which wades into the polarizing question of whether people are born gay or become so—is part of a boom in genomics research that aims to unveil how genes shape behavior, not just diseases.
Powering the new social genetics are huge databases, including the British government—funded UK Biobank and the DNA of millions of customers collected by 23andMe, a consumer gene testing company.
Study Suggests Genetic Connection to Same-sex Behavior, But Not to Genes

That could have an outsize impact on already vulnerable people, he says.
San ling massage Aldershot the work could be controversial, the team behind the new gene hunt opted to post their research plan online in They described their intent to perform a genome-wide association study, a technique originally developed to locate genetic susceptibilities to diseases like macular degeneration and diabetes.
Yet earlier attempts to identify specific genes involved were, by and large, unsuccessful. The new study is about 10 Gay Cambridge connections larger than any previous effort.
The search was two-pronged. This may be too broad, says Bailey: the researchers may Gay Cambridge connections categorized people willing to experiment sexually along with those who consider themselves gay.

Nevertheless, the researchers used the results to address the question of why homosexuality is relatively common. One possible explanation for why it is, they say, is that the same genetic factors also give a reproductive advantage to straight people who have. According to an abstract the team submitted to the American Society for Human Geneticswhose annual meeting is under way this week in San Diego, the DNA signals linked to gay sexual experiences also appeared more often in straight men who had a larger number of sex partners.

Though the genetic effects are small and their provenance uncertain, Neale continued during the press conference, the results do show that genes have a role to play in the development of sexual behavior.
