Genes linked to homosexuality discovered by scientists

Genes linked to homosexuality have been discovered by scientists in the biggest ever study into the genetic basis for sexual orientation.

For the first time, researchers looked at the complete genome - a person?s entire DNA code - for more than 1,000 gay men and compared it to genetic data from a similar number of heterosexual males.

They discovered that DNA was different for gay and straight men around the genes SLITRK5 and SLITRK6.

SLITRK6 is an important gene for brain development, and is particularly active in a region of the brain which includes the hypothalamus.

The hypothalamus is crucial for producing the hormones which control sex drive, and previous studies have shown parts of it are up to 34 per cent larger in gay men.

The researchers, from North Shore University Health System?s Research Institute, in Illinois, US, also discovered differences in the TSHR gene, which is linked to the thyroid, another area which has previously been associated with sexual orientation.

?Because sexuality is an essential part of human life ? for individuals and society ? it is important to understand the development and expression of human sexual orientation,? said lead author Dr Alan Sanders.

?The goal of this study was to search for genetic underpinnings of male sexual orientation, and thus ultimately increase our knowledge of biological mechanisms underlying sexual orientation.

Participants in the study were rated for sexual orientation based on their self-reported sexual identity and sexual feelings.

Men were asked to provide DNA by blood or saliva samples that were then genotyped and analysed.

Although previous studies have pointed to a genetic predisposition for homosexuality, it is the first time researchers have studied the entire genome of individuals and so is the most comprehensive assessment of the genetic basis of sexuality ever undertaken.

However British experts said more work was needed before it was possible to identify ?gay genes? because the genetic differences could point to other traits shared by the homosexual respondents.

For example the variations may simply predispose people to be more open or candid about their lives.

What do you think about the unavoidable consequences of what comes next? There will be gene modifications or even deleting babies with this gene. While I do believe it's an abnormality, it is still natural and I do not support going against mother nature in this case.

Science giving you an excuse for being sick; like cancer.

wow thats awesome

^ closet homosexual

Damn that's a great question. I'd be more down to genetically modify penis/boob size and height for my kids than sexual orientation. Nothing obsene just making sure they're normal. I'd also want to remove any diabetes, heart disease, Hugh blood pressure, major defects, serial killer genes Etc. The basics :1orglaugh

I think human genetic modification is the next step to our evolution. I'm not talking to Basics I'm talking scales or wings or making our bones lighter and stronger things like that.

Sometimes I wish I was gay ...

I'm guessing you're married? ;)

Are they Pink Jeans ? :helpme

Do you feel better they have discovered why you're gay, Bladewire?

You completely ignored me when I posted this, but here it is again.

As a straight person, this was the first, and only, explanation of male homosexuality that ever made sense to me

and here I thought the left was firmly against genetic modification >> GMOs

:1orglaugh

If this is true this could be amazing....


Oh bi-sexual. Doubles the potential pool of people to date.

Just saying.

^^ Truth :thumbsup Rochard is 🔥🔥🔥 & hung like a 🐎

so no medication for you, no eyeglasses, no pacemaker when your heart craps out? I'm trying to see the boundaries of what you consider to be 'natural' vrs 'unnatural'?

no kidding :thumbsup

Gays are X-men with the X-gene!

Ian McKellen: ?I was [convinced to play the role of Magneto] by Bryan [Singer, the director] who said, ?Mutants are like gays. They?re cast out by society for no good reason.??

^^ Truth

Well, it can also mean using CRISPR-CAS9 technology and VIRAL VEHICLES to target these genes in 'straight' men to turn them gay. This way sexual orientation can be an OPTION.

Movie "gattaca" is the movie which should be seen when it comes to pre-genetic engineering. But for some reason that is consider as "ethical problem" and it is described as "playing god" which is kind a stupid as i see no difference between pre-genetic engineering vs ordinary medicine administration. Plus it is already used to threat some genetic anomalies.
