Does the fact that homosexuality exists prove that sexuality is not a genetically aquired trait?

>> No.7003098

no

>what is straight-acting

>> No.7003101

No. The gay gene could be recessive, so two straight people carrying it could produce a gay child.

>> No.7003113

>>7003085
No. Any trait can have a genetic precursor.
Any trait can be based entirely on upbringing.

Nature vs. nurture, who the fuck knows.

That said, homosexuality doesn't really make sense as a trait that would be selected for in the wild, since it doesn't provide any reproductive benefit.

We do. science knows. they found the gene in april two years ago:

you get the gay from your opposed-sex parent

Less competition during mating season is an overall benefit.

>> No.7003206

The truth is, gay animals still have heterosex for procreation, so it can be selected for. Maybe a same sex parental setup is beneficial or something, who knows because our gays are socialised not to occasionally fuck women and take their babies

>> No.7003338

>>7003206
Most animals only have sex to procreate though, so calling them 'gay' doesn't really work as they don't tend to have the same types of relationships as humans.

>> No.7003356

No, because:
- Traits can positively influence the propagation of their underlying genes in all kinds of indirect ways. For example, if having gay people in your tribe positively influences the survival rates of said tribe.
- Natural selection is blind and the relation between genes and behavior is complicated, meaning that gayness can be a 'side-effect' of some complex of genetically acquired traits
- Gayness can be a recent mutation not yet selected against.

Also, I don't believe there's something like 'pure nurture', i.e. cultural explanations for behavior must always be embedded in a biological one, for the latter give the conditions and boundaries for any possible culture. Thus, in a way, all behavior is genetically acquired. Of course, people could have more 'degrees of freedom' on some areas and less on others. Conversely, probably very little behavior is totally immune for any epigenetic influences.

lots of gay men do this, too. its pretty common that a closeted fag has a wife and kids.

Well I know gay swans have babies and take them from the mothers and raise them, I think giraffes might do the same. The gay swans obviously have sex but apparently aren't under the impression they'll get kids from it

Seems more like a socially conditioned state of denial than a reproductive strategy

>another thread where people without even a high school level knowledge of genetics make claims about genetics and homosexuality

>> No.7003998

No, because if everyone wants to reproduce, there's less people to take care of kids that are resource-intensive, like humans. Queerness is a genetic disposition that is mitigated through the environment.

There are many higher-intelligence mammals who have sex for pleasure, anon. Hell, look at Bonobos. they use it as a social currency.

Having sex with men is a choice. "Feelings" are not relevant.

People are born with deformities and defects all the time. Some are less visible than others.
Not all mutations or differences serve a useful purpose. That's not how evolution works.
