Why are gay people so homosexual

The hereditary link of homosexuality has long been established, but scientists knew it was not a strictly genetic link, because there are many pairs of identical twins who have differing sexualities.

Is being gay genetic or environmental

{INSERTKEYS} [Why Are There Gay Women?] But how might the "gay man gene" make females more reproductively successful? A new study by Camperio Ciani and his team addresses the question for the first time. So if we look at the population of Americans and all of their sexual orientations, the estimate of 30 to 40 percent means that amount of the person to person variation in sexual orientation is due. The most common terms for homosexual people are lesbian for females and gay for males, but the term gay also commonly refers to both homosexual females and males.

It seems tenuous, therefore, to assert that the discovery of a genetic link for homosexuality would somehow “legitimate” gay and lesbian identity, or result in the eradication of societal discrimination against homosexual people, despite empirical evidence of an association between genetic explanations and tolerance toward gays and lesbians. When the gene was deleted in female mice, they were attracted to female odors and preferred to mount females rather than males.

His lab had previously shown that gay men in Japan were no more attentive or generous towards their nieces and nephews than straight, childless men and women. Paul Vasey, University of Lethbridge. Several hypotheses have been advanced to explain how homosexuality can be beneficial in perpetuating familial genes.

Therefore, the theory goes, a low "dose" of these alleles enhances the carrier's chances of reproductive success. 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. Despite these numbers, many people still consider homosexual behavior to be an anomalous choice. Here are the questions used for the report, along with responses, and the survey methodology.

A national survey of sexual attitudes in the UK last year , external came up with lower figures. On a regional basis, acceptance of homosexuality is highest in Western Europe and North America. Related report Jun 12, Hamer says that the findings do not reveal any biological pathways for sexual orientation. But scientific opinion is with Macklemore. The research has limitations: almost all of the participants were from the U.

Rice believes that female foetuses employ an epimark that makes them less sensitive to testosterone. For Qazi Rahman, it's the media that oversimplifies genetic theories of sexuality, with their reports of the discovery of "the gay gene". Gay people do have children. And supporters of several right-wing populist parties in Europe are also less likely to see homosexuality as acceptable. {/INSERTKEYS}

Massive Study Finds No Single Genetic Cause of Same-Sex Sexual Behavior | Scientific American

But even in countries like France and Germany where acceptance of homosexuality is high, there are differences between supporters and non-supporters of key right-wing populist parties such as National Rally in France and Alternative for Germany AfD. But even with these sharp divides, views are changing in many of the countries that have been surveyed sincewhen Pew Research Center first began asking this question.

This would compensate for gay people's lack of reproduction and ensure the continuation of the trait, as non-gay carriers of the gene pass it down. Paul Vasey's research in Samoa has focused on a theory called kin selection or the "helper in the nest" hypothesis.

However, while it took nearly 15 years for acceptance to rise 13 points from to just before the federal legalization of gay marriage in Junethere was a near equal rise in acceptance in just the four years since legalization. Nonetheless, misconceptions persist that same-sex attraction is a choice that warrants condemnation or conversionand leads to discrimination and persecution.

The new finding is consistent with multiple earlier studies of twins that indicated same-sex attraction is a heritable trait. These figures may not be people homosexual enough to sustain genetic traits specific to this group, but the evolutionary biologist Jeremy Yoder points out in a blog postexternal that for much of modern history gay why are haven't gay living openly gay lives.

In the few countries surveyed with Muslim populations large enough for analysis, acceptance of homosexuality is particularly low among adherents of Islam. Similarly, girls who have a genetic condition called congenital adrenal hyperplasia are exposed to unusually high levels of male hormones like testosterone while in the womb, which may masculinize their brain and increase the odds of lesbianism.
