Can any one provide me with absolute proof?

Question

That homosexuality is genetic? I would like to read the studies. I would like to know the background of the researchers.

please provide links

I just keep hearing that it isnt a choice because it is genetic. So I wanted to know how people KNOW it is genetic.

NemotheFish AWESOME LINK!!!! SO far you are the front runner for the points...

Answer 1

well it has not been proven with certainty that homosexuality is genetic
but that because only until recently have studies begun to surface on the topic
you know, its been taboo for a while, but now that evryone is acknowledging it
ppl are begining to study there are some groups study now like NARTH

Answer 2

Science has reached the conclusion that homosexuality has a genetic basis, but not in the way you'd think. (Since, in terms of evolution, homosexuality is a dead-end).
Homosexuality is still believed to be genetically influenced. In other animals, such as lions and bonobos (especially), homo and bisexuality are critical to the social structure.
The entire bonobo society, for example, is more or less structured around lesbians.
It is believed that these genes are still latent in human DNA, and this may be what causes homosexuality.
So yes - homosexuality may very well be genetically based.

This is only the genetic basis, however. What actually determines sexuality, it is believed, is the hormones in the olfactory gland during foetal development. If a man does not receive, for one reason or another, enough testerone in the olfactory gland during development, the development will revert to "default" - the female sexuality (since all foetuses start female). The same applies for the case of female homosexuality - too much testerone causes a "masculination" of the area of the brain that defines sexuality.
It is unknown whether this is caused purely by genetic factors, or by a hormonal reaction from the mother's body. For example, gay men are more likely to have older brothers - the theory is that the female body has a "memory" of how many males it has carried, and this produces antibodies or a hormonal disturbance that leads to the developmental sidetrack that leads to homosexuality.

What is clear, though, is that sexuality is something set at birth. This is the opinion of both scientists and psychologists. Homosexuality is, scientifically speaking, a 100% healthy and natural sexual variation, maybe not intended so much for modern humans (in the case of an evolutionary footprint), yet natural and perfectly normal part of being human nonetheless.

Answer 3

Here's the recent sheep study (LOL) that caused all the recent uproar. But you shouldn't worry about it unless you are a sheep.

But I recall an episode of Frontline or one of those Discovery Health channel programs that cited the mother's testosterone levels during her first trimester as having an effect on the brain's inferred sex (vs. physical sex). Sorry I don't have a link for that one, but it was very interesting research. I think they used rats to force a greater percentage of homosexual behavior in offspring based on manipulation of the mother's testosterone levels. Again, only a crisis for you if you're a rat.

It's really a combination of both physical and environmental stimuli. Just because you are a male for feminine tendencies or a female with male tendencies doesn't MEAN you are gay either. Effeminate men can be superior hetero lovers, and a woman who's not extremely feminine can be a wickedly hot vixen for her man.

I think it's up to each individual to decide, and I think it's wrong to think anyway has to "cure" or "correct" someone. But I also think it's equally wrong to immediately embrace someone as gay because they show traits of the opposite sex, and make them somehow think they are "meant to be" gay. It all comes down to what sex the individual finds more attractive and what roles they feel most comfortable in.

Who gives anyone the right to tell anyone else how they should live their life?

Answer 4

You're asking the impossible because, in the strictest sense, nothing can be proven absolutely.

Homosexuality is not something as simple as having blue eyes or curly hair. Like any complex human characteristic/behavior, it is likely a function of the interplay between biological (i.e., polygenetic, hormonal, neuroanatomical) and environmental influences.

If it helps, you might want to think of it in terms of intelligence, which is both genetic and environmental. A child can be conceived with all the "right stuff" to be a genius but the outcome depends a lot on how well the mother takes care of herself and what happens to the child after it is born. Does it get adequate nutrition? Stimulation? Etc.

Scientists are uncovering more and more evidence that biological factors play a large role in sexual orientation. You could easily Google these things for yourself if you wanted to, but something in your question gives me the sense that you are hostile to this research.

Let me tell you about NARTH. NARTH is a fringe group of "researchers" and "psychotherapists" who adhere to the outdated belief that homosexuality is somehow pathological. Their studies have never been found suitable for publication in any peer-reviewed journal because of sloppy methodology, questionable findings, and dubious ethics - yet they continue to claim that homosexuality is disordered and can be cured.

The vast majority of researchers, psychologists, and therapists recognize that there is nothing innately disordered, inferior, or harmful about homosexuality.

Answer 5

Not yet, no. Scientific research is still being conducted. Can you wait a while?

Everyone that keeps saying "I know someone who . . . " . . . that's not evidence or absolute proof. If that's the case, I could absolutely prove all of you wrong with the examples of people I know personally whose families have several homosexuals.

EDIT: Wow. Had I known that you were unable to understand what a credible organization was, I wouldn't have bothered answering the question. That link you said was "awesome" . . . yeah, it's created by a group that believes homosexuality can be cured as if it is some kind of disease.

Clearly, you didn't want an answer. You wanted someone to agree with you. I'll pack my things and go. I have no interest in a complete disregard for truly unbiased scientific research.

Answer 6

I've never read any real study that did real tests that came up with those findings. There are alot of reasons why people are the way they are but that particular thing is only been proved to be less genetic and more how one is raised. Where as gender is more Genetic then how one is raised. It's part of the nature and nurture studies.

They say that actually smarter people are prone to be homosexual just because they are more open to new and different ideas, where as people who aren't as smart (IQ level that is) are normally heterosexual, that goes the same way with bisexual people as well.

Answer 7

It is not a choice. If homosexuality is a choice...then so is heterosexuality. Think about it... If every homosexual chose to be gay, then every heterosexual could choose to be gay also. I have read studies where they brain activity of a gay man acted the same of a straight woman when the pheremones of a man were intoduced. Everyone talking about gay kids and straight parents...that is heredity...not genetics. The brain responds to diferent people in different ways and there is no way to change that...Ask yourself if you are choosing to be straight or if someone of the same sex just doesn't do it for you.

Answer 8

http://en.wikipedia.org/wiki/Biology_of_sexual_orientation

That's a link I like, it gives a good rundown. The thing is though, even though it's not a choice, it's unknown if it's genetic or not.

Something causes it, but it's not clear it seems. Some studies point to genes, others point to hormonal differences.

Either way, if you get a choice, by definition that's bisexuality. We're not all afforded the luxury of that gift, so we have heterosexual on one end of the scale and homosexual/lesbian on the other.

It seems to serve some purpose though, otherwise it wouldn't exist at all. Nature cannot create anything unnatural.

Answer 9

It could be genetic or one other thing, or maybe a combination of many things. Homosexuality is a really mysterious and broad aspect out there. Some even say that it could be a result of stress during pregnancy, hormones, influence, and now even environmental pollution. It's really difficult to say.

Answer 10

Research has been going on for decades to find a genetic cause for homosexuality. They haven't found one yet (but that doesn't mean it isn't there, of course)

What makes you think anyone here has the answer that has eluded so many geneticists and medical researchers for so long?

Answer 11

Check out twin studies. Identical twins have identical DNA. There is a higher incidence for correlated sexual preference but it is not 100%. Clearly there are genetic factors but environment must also play a role. This is also found in twin heights, normally they are the same but not always. I should emphasize here that no science backs up the misconception that it is a "choice" any more than being tall is a choice.
