Stop calling it a choice Biological haldol decanoate 100 mg factors drive homosexuality – MambaOnline – Gay South Africa online

Numerous studies have established that sex is not just male haldol decanoate 100 mg or female. Rather, it is a continuum that emerges from a person’s genetic makeup. Nonetheless, misconceptions persist that same-sex attraction is a choice that warrants condemnation or conversion, and leads to discrimination and persecution.

I am a molecular biologist and am interested in this haldol decanoate 100 mg new study as it further illuminates the genetic contribution to haldol decanoate 100 mg human behaviour. As the author of the book, pleased to meet me: genes, germs, and the curious forces that make us who we are, I have done extensive research into the biological forces that haldol decanoate 100 mg conspire to shape human personality and behaviour, including the factors influencing sexual attraction. The hunt for ‘gay genes’

The new study is the latest in a hunt for haldol decanoate 100 mg “gay genes” that began in 1993 when dean hamer linked male homosexuality haldol decanoate 100 mg to a section of the X chromosome. As the ease and affordability of genome sequencing increased, additional gene candidates have emerged with potential links to homosexual haldol decanoate 100 mg behaviour. So-called genome-wide association studies identified a gene called SLITRK6, which is active in a brain region called the diencephalon haldol decanoate 100 mg that differs in size between people who are homosexual or haldol decanoate 100 mg heterosexual.

Genetic studies in mice have uncovered additional gene candidates that haldol decanoate 100 mg could influence sexual preference. A 2010 study linked sexual preference to a gene called haldol decanoate 100 mg fucose mutarotase. When the gene was deleted in female mice, they were attracted to female odours and preferred to mount haldol decanoate 100 mg females rather than males.

Other studies have shown that disruption of a gene called haldol decanoate 100 mg TRPC2 can cause female mice to act like males. Male mice lacking TRPC2 no longer display male-male aggression, and they initiate sexual behaviours toward both males and females. Expressed in the brain, TRPC2 functions in the recognition of pheromones, chemicals that are released by one member of a species haldol decanoate 100 mg to elicit a response in another.

With multiple gene candidates being linked to homosexuality, it seemed highly unlikely that a single “gay” gene exists. This idea is further supported by the new study, which 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. How might these genes influence same-sex behaviour?

I find it intriguing that some of the genes from haldol decanoate 100 mg men identified in ganna’s study are associated with olfactory systems, a finding that has parallels to the work in mice. Ganna’s group found other gene variants that may be linked haldol decanoate 100 mg with sex hormone regulation, which other scientists have previously suggested plays a large role haldol decanoate 100 mg in shaping the brain in ways that influence sexual behaviour.

Males with a genetic condition called androgen insensitivity syndrome can haldol decanoate 100 mg 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. This suggests that testosterone is needed to “masculinize” a prenatal brain; if that doesn’t happen, the child will grow up to desire men.

Similarly, girls who have a genetic condition called congenital adrenal hyperplasia haldol decanoate 100 mg are exposed to unusually high levels of male hormones like haldol decanoate 100 mg testosterone while in the womb, which may masculinize their brain and increase the odds of haldol decanoate 100 mg lesbianism.

It’s also possible that hormonal shifts during pregnancy could affect haldol decanoate 100 mg how a fetus’ brain is configured. In rats, manipulation of hormones during pregnancy produces offspring that exhibit homosexual haldol decanoate 100 mg behaviour. Why does homosexual behaviour exist?

Several hypotheses have been advanced to explain how homosexuality can haldol decanoate 100 mg be beneficial in perpetuating familial genes. One idea involves the concept of kin selection, whereby people work to ensure the passage of their family’s genes into subsequent generations. Gay uncles and aunts, for example, are “ helpers in the nest” that help raise other family members’ children to nurture the family tree.

Sexual behaviour is widely diverse and governed by sophisticated mechanisms haldol decanoate 100 mg throughout the animal kingdom. As with other complex behaviors, it is not possible to predict sexuality by gazing into haldol decanoate 100 mg a DNA sequence as if it were a crystal ball. Such behaviors emerge from constellations of hundreds, perhaps thousands, of genes, and how they are regulated by the environment.

While there is no single “gay gene,” there is overwhelming evidence of a biological basis for sexual haldol decanoate 100 mg orientation that is programmed into the brain before birth based haldol decanoate 100 mg on a mix of genetics and prenatal conditions, none of which the fetus chooses.
