Half of us have 'Gay genes' and larger a family, a Gay son
Half of us have 'gay genes' and the larger a family, the greater the chance of having a homosexual son, controversial study claims
- Researchers used a computer model to study prevalence of homosexuality
- Previous research found orientation is influenced by genes to a degree
- This poses a problem from an evolutionary perspective, because gay men tend to have fewer offspring to whom they can pass on their genes
- As a result, half of us must have 'gay genes' for homosexuality to remain
- However, the researchers did not identify any specific genes
Quote:
Around half of straight men and women potentially carry so-called homosexuality genes that are passed on from one generation to the next, according to new research.
This has helped homosexuality exist among humans throughout history, even though gay men tend to have fewer descendants who directly inherit their genes.
The researchers came to this conclusion using a computational model that, among others, included aspects of heredity and the tendency of homosexual men to come from larger families.

However, the researchers did not identify any specific genes and instead the conclusions are based on the fact homosexuality must have a hereditary element.
This idea is reported by Giorgi Chaladze of the Ilia State University in Georgia, and published in Springer's journal Archives of Sexual Behaviour.
According to previous research, sexual orientation is influenced to a degree by genetic factors and is therefore heritable.

THE CLAIMS OF A 'GAY GENE' - According to previous research, sexual orientation is influenced to a degree by genetic factors and is therefore heritable.
- This poses a problem from an evolutionary perspective, because homosexual men tend to have fewer offspring to whom they can pass on their genetic material.
- Other reports also suggest many heterosexual men are carriers of the genes that could predispose someone to homosexuality.
- Based on the researcher's calculations, male homosexuality is maintained in a population at low and stable frequencies if half of the men and roughly more than half of the women carry genes that predispose men to homosexuality.

Chaladze used an individual-based genetic model to explain the stable, yet persistent, occurrence of homosexuality within larger populations.
He took into account findings from recent studies that show that homosexual men tend to come from larger families.
These suggest the genes responsible for homosexuality in men increase based on the number of children someone has.
And this applies to large families that have both sons and daughters, because females also carry the genes.
Other reports also suggest many heterosexual men are carriers of the genes that could predispose someone to homosexuality.
Based on Chaladze's calculations, male homosexuality is maintained in a population at low and stable frequencies if half of the men and roughly more than half of the women carry genes that predispose men to homosexuality.

Quote:
The possibility that many heterosexual men are carriers can also explain why estimates of the number of men who have reported any same-sex sexual behaviour and same-sex sexual attraction are much higher than estimates of those who self-identify as homosexual or bisexual.
According to Chaladze, non-homosexual male carriers might sometimes manifest interest in homosexual behaviour without having a homosexual identity.
The possibility that a large percentage of heterosexual people are carriers of genetic material predisposing to homosexuality has implications for genomic studies.
Researchers should therefore consider including participants who do not have homosexual relatives in such studies.

Is there a Gayncestry dna test we can take?

Wouldn't it make sense for homosexuality to exist from an evolutionary stand point. Meaning, it can be a form of population control? Like rabbits for instance breed like crazy, but they have many predators. Humans don't have many natural predators so there is no way to control there growth. Also, I heard one possible idea that during the primitive days, homosexual men stayed with the women to protect them while the men went and hunted.

So is this implying that gay men will pass their sexuality onto their children? :/

not necessarily. I think in this theory both the mother and father would have to have the "gay gene" in order for the child to turn out gay, so if a gay man had a baby with a straight woman that didn't have the gay gene, the child wouldn't be gay, but would still have the gay gene to pass on. I don't really believe in this though, I think a person's sexuality has more to do with hormones they're exposed to while in the womb

Personally, I don't think it has any evolutionary advantage. Homosexuality just is.
I also think it's due to hormones, not necessarily a "gene".

What kind of Mendelian genetics mess 
The guys in that stock photo look adorable together.

I agree. It doesn't at all, more like a disadvantage since the the basic point of life is to reproduce. I read somewhere that homosexuality could also be a hormonal thing. Since we all start as females, then testosterone kicks in later causing males to develop those traits. Exact reason why males have nipples. So maybe it could've been something in the womb. But the who point is, we really don't know.

What...? Does that mean there are genes that give you a preference to say blondes, Asians, tall people, even a gene for pedophiles? Makes no sense to me..

I've always thought of this too, homosexuality is great for population control. If the world's population keeps growing at the rate it is, in a few centuries homosexuality will be valued and seen as a blessing in disguise.
