The gay gene

[bythoughts]

I don't want it in my search history, so I am asking you. What are "wet nuts"?

Well, you hand your boyfriend a little bowl of melted ice cream...

 

[CLAX1911]

There could be other factors such as environmental, diet, upbringing etc. etc...

Not saying any of those are a factor just that it isnt necessarily genetic or a choice

Agreed

 

[madman]

As we always knew, being gay is a lifestyle choice, people are not born gay, and science has proven this.

The question now becomes; how do we change society to correct this abnormal behavior?

• No single "gay gene" determines sexual orientation.
  Research, including the largest study of its kind, involving nearly half a million people, has concluded that there is no singular gene responsible for being gay.
  Sexual orientation is influenced by a combination of factors:
  • Genetics: While not solely determined by genetics, genes play a role, contributing to a portion of the variation in same-sex sexual behavior. Studies have identified specific genetic variants associated with same-sex behavior, but their individual effects are small.
  • Environment: Non-genetic or environmental factors, which can include things like prenatal influences, also play a significant role in shaping sexual orientation.
  • Other Biological Factors: Research suggests other biological factors may also be involved, such as prenatal hormone exposure, maternal immune response, and neuroanatomical differences in the brain.
• It is effectively impossible to predict an individual's sexual behavior from their genome. The study suggests that, at best, genetic variants can only predict a small portion of the variation in sexual behavior within a population.
  Important Notes:
  • This research emphasizes that the diversity of sexual behaviors is a natural part of human variation.

Firstly what reason is there to care other than idle curiosity? (which I´m all for btw)

Secondly twin studies would suggest that homosexuality is somewhere between 60 and 80 % genetic. Either way, why not just let people be in love with who they want to?

Twin studies prove other wise there is genetic predisposition. Identical twins are both gay 53% fraternal twins 42% non twin siblings 23%. The progression of the genes show a clear genetic factor. Enter epigenetics. A gene in some cases must be turned on by experiences during development. We dont know what it is. Its part of our adaptability. In any case its defied ass normal in psychology and was removed form the DSM in 1974

 

[Marvin Klein]

Yes the genes determining homosexuality are epigenetic. They require a trigger to activate them. We dont know what that is but it appears to be constant 2-3% across all cultures

 

[digsbe]

I think an epigenetic theory makes a lot of sense. It may also have to do with the androgen environment in the womb a fetus is exposed to as well as maternal antibodies potentially blocking androgen action. It is well documented that there is the birth order effect, meaning with every male a woman gives birth to there is a higher chance of having a gay male son. The belief is because a mother is almost "immunized" against certain androgen receptors and may be antagonized by maternal antibodies that a mother makes with concurrent exposure to male fetuses. We know that androgen are required to masculinize the brain which leads to male heterosexuality. Homosexual males show sex-reversed brain physiology and for epigenetic, maternal immune response, or hormone exposure a gay male's brain is left feminized meaning their reproductive instincts are towards other men. Homosexuality is certainly biologically caused.

 

[bomberfox]

A small factor.

Not the deciding one meaning it can be changed.

Serial killers have a small killer gene also so should we just let them kill away?

I think not.

Wow…..

 

[bomberfox]

There is no one specific gay gene that is activated but there are genetic determinants for being gay. Its not something you really choose.

 

[Gordy327]

Indeed. Whenever someone says homosexuality is a choice, I ask when did they choose to be straight.

 

[CLAX1911]

Yes it was something you could choose I wouldn't be. And I don't think many gay people would be.

 

[Real blank]

There isn’t gonna be a gay gene. There isn’t going to be a specific gene. Genes don’t work that way for such a complicated behavior. It’s like saying “Did Michael Jordan have the basketball gene”

Had to look that up but, seems to just suggest one gene can cover more than on thing.

I learned about it looking at sickle cell anemia. Sickle cell is a byproduct of blood that is malaria resistant. Sickle cell is a side effect of a gene that creates blood that resists malaria. 99999 times out of 100000 a person with this Gene gets malaria resistant blood one time out of 100000 they get sickle cell.

Still a human behaviour like sexuality seems more complex than identifying a gene.

Agreed there's probably a lot more to it than just a genetic predisposition and that's what I would think it would be if genetics play any role at all.

I’ve definitely known straight men who are a bit gay and vice versa.

 

[CLAX1911]

I’ve definitely known straight men who are a bit gay and vice versa.

I would think some fellows may be a bit curious either way and then some guys are bisexual.

 

[Jason Warfield]

Exactly my point.

Nobody is born gay.

And nobody is born straight.

Unfortunately, the numbers aren't that great. According to https://pmc.ncbi.nlm.nih.gov/articles/PMC6858853/ about 15% of Sub-Saharan Africans have sickle cell trait. The math on that is 2x(1-x) = 0.15 x(1-x) = 0.075 x^2 - x + 0.075 = 0 1/2 +- sqrt(1-0.3)/2 = 0.0817. So you have 8.17% of all the hemoglobin genes in the area with sickle cell trait. There MUST be an 8.17% x 8.17% = 0.667% chance of having sickle cell anemia, in exchange for the 15% = 8.17% x 91.83% + 91.83% x 8.17% chance of inheriting one sickle gene (on either chromosome) and one ordinary gene, and then there is a 91.83% x 91.83% = 84.33% chance of having two ordinary genes. So there's one person with sickle cell anemia for every 22 people protected from malaria.

 

[Gardener]

There does not need to be a gene because there is nothing that needs justification.


People should limit themselves to worrying about behavior that is harmful.

So there's one person with sickle cell anemia for every 22 people protected from malaria.

What I've read says 8% are the carriers. And then people actually afflicted with it are rare among the carriers.

There's one person that's a carrier of the alleles for sickle cell anemia for every 22 people protected from malaria there is not one person for every 22 people infected with him while you're at that's actually afflicted with sickle cell anemia.

What's the percentage that a carrier is actually afflicted?
