But geneticists have had only a handful of underpowered studies to address a complex, fraught, and often stigmatized area of human behavior. Now, the largest-ever study of the genetics of sexual orientation has revealed four genetic variants strongly associated with what the researchers call nonheterosexual behavior.

Some geneticists are hailing the findings as a cautious but significant step in understanding the role of genes Cambridge bissau sex sexuality. Others question bjssau wisdom of asking the question in the first place. Andrea Ganna, a research fellow with the Broad Institute Cambridgw Cambridge, Massachusetts, and Harvard Medical School in Boston, and colleagues examined data from hundreds of thousands of people who provided both DNA and behavioral information to two large genetic surveys, the UK Biobank study and the private genetics firm 23andMe.

The researchers performed a genome-wide association study GWAS in which they looked for specific variations in DNA that were more common in people who reported at least one same-sex sexual experience. They identified four such variants on chromosomes seven, 11, 12, and 15, respectively.

Two variants were specific to men Massage on the go St. Catharines reported same-sex sexual experience. One, a cluster of DNA on chromosome 15, has previously been found to predict male-pattern baldness.

Another variant on chromosome 11 sits in a region rich with olfactory receptors.

Ganna noted that olfaction is thought to play a large role in sexual attraction. A much smaller study, which used a different kind of association technique known as a genetic linkage Cambridge bissau sex, had suggested a stretch of DNA on the X chromosome was linked to inherited homosexuality. In the new GWAS, that stretch was not found to be associated with the reported same-sex behavior. But the lead author of the earlier study, Dean Hamer, then of the National Institutes of Health in Bethesda, Maryland, praised the new work.

The four newly Barrie arie beautiful genetic variants also were correlated with some mood and mental health disorders. Both men and women with the variants were more likely to have experienced bbissau depressive disorder and schizophrenia, and women were more likely to have bipolar disorder. Ganna stressed that these findings should not be taken to mean that the variants cause the disorders.

Cambriddge Ganna noted that the correlation with schizophrenia and risk-taking behavior was more pronounced in the UK Biobank participants, who tend to skew older than those in the 23andMe group. That could be because older generations faced more sexual discrimination than younger ones, Ganna said, Sexual massages Jonquiere that environment likely plays a significant role in which traits wind up correlating with sexual orientation.

That could help explain why these variants might stick around in populations even if people attracted to the same sex tend to have fewer children than heterosexuals. Ganna did not touch on that finding in his talk, citing lack of time. By Jeffrey Mervis Cambridge bissau sex. By Dalmeet Singh Chawla Nov. All rights Reserved. Got a tip?
