Physiologically a spectrum is actually more accurate because sexuality is likely determined through epigenetics.

That is, there are some number of genes which make a person feel attraction towards M or F. Effectively everyone has the same sexual attraction genes. We are supposed to have our opposite sex attraction genes turned on and the same sex attraction genes turned off otherwise reproduction wouldn't work and the species would die off.

Genes get turned on or off through complicated chain reactions and it's extremely unlikely that any particular gene can be hard set to the off position. It's just that one attraction ends up overwhelming the other and the person becomes effectively locked onto a single sex.

Which are those genes?

What are you asking? As far as I'm aware we only know of 2 and both of those relate to gay males. One is on the X chromosome and a certain version of the gene is linked to both female "fertility" and male homosexuality. They called it fertility but that seems misleading. It's basically a gene that makes a person more horny for men which explains why women with that version have more children and men are more likely to be gay.

Whatever the other gene is idk, and whatever other number of sexuality genes exist idk and we might not ever find them if they serve multiple purposes.

I though my question was clear. Hey let me clarify : Link me to the study/ies identifying those gay genes. Because I am a Biologist and I think that if there was a clear scientific consensus on the existence of "gay" genes,I would have heard of it.But maybe I missed it.So...link?

There are other studies which claim to refute the idea of a genetic link but for some reason i see them declaring "there is no SINGLE gene" that makes someone gay and act surprised that it doesn't line up for men and women but it's like... Yeah no shit...

To sum up no gay genes were identified.

Ok? I never said there was a "gay gene". That framing is entirely wrong. That's the same silly framing the counter studies use. Do you need me to rephrase my statement to say that the specific gene was not isolated or can you stop the pedantic hair splitting?

Results, especially in the context of past studies, support the existence of genes on pericentromeric chromosome 8 and chromosome Xq28 influencing development of male sexual orientation.

It specifically found 2 regions of interest. I know it isn't "scientific" to assume that sexuality is affected by more than the 2 but I'll do so anyway and that assumption is way more sound than trying to assume it would need to be a single gene like the other papers seem to do.

These are your own words :

That is, there are some number of genes which make a person feel attraction towards M or F. Effectively everyone has the same sexual attraction genes. We are supposed to have our opposite sex attraction genes turned on and the same sex attraction genes turned off

You claimed there is a number of genes controlling sexual attraction and that everyone has the same sexual attraction genes. In reality no genes controlling sexuality have been identified. Have a very nice day.

They literally point to the regions where the genes are located. Saying that the specific gene wasn't isolated is irrelevant and it obviously does not mean that the genes don't exist. That's like saying my house doesn't exist because i I've only revealed that I live somewhere in the US.

Whatever dude.
