The simple idea of a “gay gene” has been replaced by a more complex scientific view. I am a molecular biologist and am interested in this new study as it further illuminates the genetic contribution to human behavior. Males with a genetic condition called androgen insensitivity syndrome can develop female genitalia and are usually brought up as girls, despite being genetically male — with an X and Y chromosome — and they are attracted to men.
文献调研、实验、整理数据、撰写等等这些相信大家都经历过或者正在经历，但在投第一篇文章之前，你了解过SCI论文投稿的状态吗？是没有编辑受理，还是压根就没有被期刊查收呢？下面. Genetic studies in mice have uncovered additional gene candidates that could influence sexual preference.

The 'Gay Gene' Is A Myth But Being Gay Is 'Natural,' Say ...
. So-called genome-wide association studies identified a gene called SLITRK6which is active in a brain region called the diencephalon that differs in size between people who are homosexual or heterosexual. Twin studies of homosexuality have shown that identical twins are about twice as likely to both be gay compared to fraternal twins.
Indiana University provides funding as a member of The Conversation US. In the U. Despite these numbers, many people still consider homosexual behavior to be an anomalous choice.

A study linked sexual preference to a gene called fucose mutarotase. being 表示人的情感\本质——your mind and all of your feelings.
That’s the first thing you need to know about the largest genetic investigation of sexuality ever, which was published. 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. Nonetheless, misconceptions persist that same-sex attraction is a choice that warrants condemnation or conversionand leads to discrimination and persecution.
In rats, manipulation of hormones during pregnancy produces offspring that exhibit homosexual behavior. The new finding is consistent with multiple earlier studies of twins that indicated same-sex attraction is a heritable trait. Since then more and more research has revealed that same-sex sexual behavior is influenced by multiple genes and environmental factors. Learn about the causes and reasons for being gay.
This idea is further supported by the new studywhich identified five new genetic loci fixed positions on chromosomes correlating with same-sex activity: two that appeared in men and women, two only in men, and one only in women.
There is no 'gay gene.' There is no 'straight gene ...
The relationship between biology and sexual orientation is a subject of ongoing research. Several hypotheses have been advanced to explain how homosexuality can be beneficial in perpetuating familial genes. You are being too modest. being什么时候用？ You are too modest.
Is Biological Determinism on its Way Out? - Juicy Ecumenism
Estimates as to the number of gay people in the population range from 1-in to 1-in, so why are some people gay? However, biologists have documented homosexual behavior in more than speciesarguing that same-sex behavior is not an unnatural choice, and may in fact play a vital role within populations. There is no single gene responsible for a person being gay or a lesbian. Are they gay by choice or is being gay genetic?
Twin studies of homosexuality have shown that identical twins are about twice as likely to both be gay compared to fraternal twins. Explore the nuanced biological factors that influence human sexuality. I hated Stefan with my whole being. The simple idea of a “gay gene” has been replaced by a more complex scientific view. Male mice lacking TRPC2 no longer display male-male aggression, and they initiate sexual behaviors toward both males and females.
While scientists do not know the exact cause of sexual orientation, they theorize that it is caused by a complex interplay of genetic, hormonal, and environmental influences. In a issue of Science magazinegeneticist Andrea Ganna at the Broad Institute of MIT and Harvard, and colleagues, described the largest survey to date for genes associated with same-sex behavior. This means that being gay is partly genetic, and not simply something that a person learns or chooses.
Being理所应当地成为了实在的根本和终极要素。 当巴门尼德把“being”当作一个特殊的“什么”来予以追问，这就开创了本体论的传统。 巴门尼德推论的关键在于利用希腊语中eimi具有“是”（系 .

Other studies have shown that disruption of a gene called TRPC2 can cause female mice to act like males. Why are people gay? Are they gay by choice or is being gay genetic? As the ease and affordability of genome sequencing increased, additional gene candidates have emerged with potential links to homosexual behavior.
[1][2][3] However, evidence is weak for hypotheses that the postnatal social environment impacts sexual orientation, especially for. Expressed in the brain, TRPC2 functions in the recognition of pheromones, chemicals that are released by one member of a species to elicit a response in another.
