New study finds there is no ‘gay’ gene

A new major study found there is no “gay” gene for homosexuality.

The study examined data from several large genetic databanks in multiple countries, and surveyed nearly half a million people about their sexual partners and preferences. Previous studies on whether same-sex orientation and behavior has a genetic basis have only examined sample groups of hundreds of people.

Melinda C. Mills, a professor of Sociology at the University of Oxford, summarized the study in “How do genes affect same-sex behavior?” on August 30, 2019, in Science, vol. 365, issue 6456, pp. 869-870:

Studies have indicated that same-sex orientation and behavior has a genetic basis and runs in families, yet specific genetic variants have not been isolated (1). Evidence that sexual orientation has a biological component could shape acceptance and legal protection: 4 to 10% of individuals report ever engaging in same-sex behavior in the United States, so this could affect a sizeable proportion of the population (2). On page 882 of this issue, Ganna et al. (3) report the largest study to date, comprising almost half a million individuals in the United Kingdom and United States, identifying genetic variants associated with same-sex sexual behavior. They provide evidence that genetic variation accounts for a small fraction of same-sex sexual behavior and uncover a relationship to the regulation of the sex hormones testosterone and estrogen as well as sex-specific differences. They also reveal complexity of human sexuality.

The study by four scientists was led by Andrea Ganna, a geneticist at the Broad Institute of MIT and Harvard; the findings are published as “Large-scale GWAS reveals insights into the genetic architecture of same-sex sexual behavior” in Science, vol. 365, issue 6456. Below is the abstract:

Twin and family studies have shown that same-sex sexual behavior is partly genetically influenced, but previous searches for specific genes involved have been underpowered. We performed a genome-wide association study (GWAS) on 477,522 individuals, revealing five loci significantly associated with same-sex sexual behavior. In aggregate, all tested genetic variants accounted for 8 to 25% of variation in same-sex sexual behavior, only partially overlapped between males and females, and do not allow meaningful prediction of an individual’s sexual behavior. Comparing these GWAS results with those for the proportion of same-sex to total number of sexual partners among nonheterosexuals suggests that there is no single continuum from opposite-sex to same-sex sexual behavior. Overall, our findings provide insights into the genetics underlying same-sex sexual behavior and underscore the complexity of sexuality.

Speaking to Scientific American, Eric Vilain, a geneticist at Children’s National Health System in Washington, D.C., called the study’s result “the end of the ‘gay gene’” theory.

Ed Condon reports for Catholic News Agency, Aug. 30, 2019, that Vanna, et al.‘s research showed five distinct genetic data points which appear common among individuals who reported at least one same-sex encounter. Two of these markers appear linked to hormones and smell, factors in sexual attraction. But the five markers together explained less than 1% of differences in sexual activity among the population.

Dr. Kevin Miller, assistant professor of theology at Franciscan University in Steubenville, Ohio, told CNA that the results are in accord with the Catholic Church’s existing teaching about homosexuality: “The Catechism treats homosexuality in nos. 2357-2359. Early in this treatment we read that its ‘psychological genesis remains largely unexplained.’ The new study does not change this.”

Miller said the Catechism teaches that the homosexual tendency or inclination itself is not “morally wrong,” since a person does not choose to have an inclination, but homosexual acts are “intrinsically disordered” and “under no circumstances can they be approved” because only sexual acts oriented by their nature to the possibility of procreation and set within marriage are “compatible with the essential moral virtue of chastity and . . . love.” And so even if a person has an interior disposition toward engaging in homosexual acts, they have the same freedom to pursue them or not.

Long time ago in the neighborhood, there were fraternal male twin brothers born to a well to do family, one a writer the other a surgeon, both were gay, one died of aids. It was a well kept “secret” and everybody respected that family.

Human behavior, and especially sexual behavior, is formidably complex. To ascribe homosexuality to a “gay gene” is simplistic, reductive, and just stupid. For some time now the atheist/materialists have been promoting the idea that there is a “gene for” almost everything. Behavior patterns have predominantly psychological origins, with “genetic” influences to be sure, but these influences are an aggregate of which genes are expressed, conditioned by immensely complex interactions between gene regulatory networks. So they finally knocked the gay gene on the head. It’s about time. I’ll have to send this to my sodomite half-brother. I don’t know why I… Read more »

These homosexual “idiosynchrisities”…..& their so-called intellectual “ideas”/ theories / “guesses”……are devoid of morality, of which this society exists…..& without “Morality”, we have just another Sodom & Gomorrah….{ plain, & simple}……{homosexuals, “most of them”….have “no boundaries on moral behavior}

Why isn’t that degenerate scumbag in the picture being arrested for exposing himself to little children?

“there is no single continuum…”
Yeah, but somehow I doubt we’ll stop hearing that tiring phrase of LGBTQ-ology. Or having 40-odd choices for gender on Facebook.

The Human Genome Project already proved there’s no such thing as a gay gene. This study independently confirms it.

Of course there isn’t a gay gene. That is why there are so many grooming attempts on young children such as drag queen story hour.

Harvard study?….Hummmm….that’s where “King Obama”….{ aka Bath House Barry}….got his ‘so-called” edumacation, in the Constitutionality of the law?….:O}……Hummm….Wonder if Barry is still “queer”?…..”Gay”…..”sittin on the fence”?…….out a da closet?……..or “what”? Moochelle….You got anything to say about this?

What a very sad state of affairs, in America, redefining marriage…..accepting, & embracing homosexuality….{ even in the Supreme Court?}……Sorry God……Can you forgive them?

This will finally finish my discussion with my daughter by admitting I’m wrong and she is correct! Damn!!
Now it’s on to Global Warming!! I know I’m correct on this one!!

They’d had better luck finding the liberal gene.
On the other hand though, eating from the tree of knowledge still doesn’t make us intelligent enough to understand the Creator’s methods or reasons.
Liberialism as well as homosexuality are mental disorders.
