I t turns out that genetics is almost as complicated as love and sex. But while the research may be interesting, it is surely irrelevant. Believing that LGBTQ people choose their sexuality belongs in the same bin as flat-Earthism and climate emergency denial.
CHICAGO — The largest study of its kind found new evidence that genes contribute to same-sex sexual behavior, but it echoes research that says there are no specific genes that make people gay. The genome-wide research on DNA from nearly half a million U. The variants were more common in people who reported ever having had a same-sex sexual partner.
How do genes influence our sexuality? The question has long been fraught with controversy. An ambitious new study — the largest ever to analyze the genetics of same-sex sexual behavior — found that genetics does play a role, responsible for perhaps a third of the influence on whether someone has same-sex sex.
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 and 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 Details of the unpublished study have been described in a public research plan, in two scientific abstracts, and by researchers at a scientific meeting held in June at the Broad Institute, a genome research center in Cambridge, Massachusetts.
And it helps clarify where the priorities of LGBTQ people should be in fighting for civil rights in the political and legal arenas. Such fears are understandable. And while it does conclude that genetics play a role in same-sex attraction, it also concludes that environmental and social factors play a large role as well.

The relationship between biology and sexual orientation is a subject of research. While scientists do not know what determines an individual's sexual orientationthey theorize that it is caused by a complex interplay of genetichormonaland environmental influences. Biological theories for explaining the causes of sexual orientation are favored by scientists.
By Tina Hesman Saey. August 29, at pm. Updated August 30, at pm. Publication of the largest-ever study of the roles of genes in homosexual behavior is fanning the debate over whether being gay is due to genes or environment.
Homosexuality is romantic attraction, sexual attractionor sexual behavior between members of the same sex or gender. It "also refers to a person's sense of identity based on those attractions, related behaviors, and membership in a community of others who share those attractions. Along with bisexuality and heterosexualityhomosexuality is one of the three main categories of sexual orientation within the heterosexual—homosexual continuum.
Few aspects of human biology are as complex—or politically fraught—as sexual orientation. Now, a new study claims to dispel the notion that a single gene or handful of genes make a person prone to same-sex behavior. The analysis, which examined the genomes of nearly half a million men and women, found that although genetics are certainly involved in who people choose to have sex with, there are no specific genetic predictors.
