Is homosexuality genetic?

Question

If so, please provide evidence, not feelings. Thanks

Answer 1

LOL!

If it were genetic, then they would not mate, and not pass their genes to children. Therefore, it is impossible for it to be a genetic trait. Some of us payed attention in biology class.

There is also the obvious fact that homosexuality is an action, not a trait or characteristic. Any action is a choice, like walking, jumping, driving a car, or having sex. Genes will give you legs, but they will not make you walk, you have to choose to perform that action. Genes will give you genitals, but they will not make you have sex, that is an action you have to choose to engage in.

It doesn't get any more obvious than that.

Answer 2

Well Alex there is still no definitive study that I'm aware of that can considered emperical, but what we can do is draw conclusions from a perponderance of evidence , first being anecdotal, homosexuals state this is the case, but here are the conclusions of a study that I found a little disturbing but nonetheless interesting, source cited in post, keep in mind there are more than just one study one point to that combined with the anecdotal suggest indeed this is true

Homosexuality in men and number of older brothers
R Blanchard and AF Bogaert
Clarke Institute of Psychiatry, Toronto, Ontario, Canada.

OBJECTIVE: This study investigated whether homosexual men have a higher mean birth order than heterosexual men primarily because they have more older brothers or because they have more older siblings of both sexes. METHOD: For the main analyses, 302 heterosexual men were individually matched on year of birth with an equal number of heterosexual men. Each completed a self-administered, anonymous questionnaire concerning family background and other biodemographic information. RESULTS: Logistic regression analysis showed that homosexuality was positively correlated with the proband's number of older brothers but not with older sisters, younger brothers, younger sisters, or parental age at the time of the proband's birth. Each additional older brother increased the odds of homosexuality by 33%. CONCLUSIONS: These results restrict the range of possible theories of the birth order phenomenon to those that can explain not only why older brothers increase the probability of homosexuality in later-born males but also why older sisters neither enhance this effect nor counteract it.

Answer 3

I don't think there is any proof available either for or against that premise.

I would doubt that it is genetic in the sense that it is passed on from parent to child. I do believe that it is genetic in the sense that something in a person's genes makes them homosexual--e.g. its not a choice.

Answer 4

Can you force yourself to be gay, feel sexual desire for other males? If it was not genetic, you would be able to.

Hmmm, I wonder if you have a homosexual male and female with a child, if the child is generally gay? Is it the same chromosome for males and females? I might be able to get government funding for this!

If you really want to be educated, read that article. I don't think giraffes choose to be gay.

Also, why would anybody choose to be gay and deal with society's hatred/disdain to them? There's obviously no proof of that, but think about the logic and you'll get it.

Have you ever heard of recessive genes? Two blonde-haired, blue-eyed, tall parents can have an albino midget kid with red eyes.

Apparently he didn't pay enough attention to learn of recessive genes either.

Answer 6

Yes
"Nobody in science now believes that sexual orientation is caused by events in adolescence...Homosexuality is an early, probably prenatal and irreversible preference." Author and geneticist Matt Ridley

Answer 7

I think you mean congenital, not genetic. People in the gay and lesbian topic could enlighten you with some details and "evidence"

Answer 8

i am about as right wing as they come but it seems clear to me that people are born gay or strait. i dont mean it to sound hateful but i (honestly) believe it to be a defect whereby a person is born not entirely a male or entirely female. no one reasons their way into sexuality (gay or strait), it is a compulsion. this is why even people who dont want children often have sex.
i often ask my Conservative, male friends who believe it is a choice if they can choose to find men sexually compelling even for 10 seconds or at gunpoint. of course they cannot.

Answer 9

There is no proof that its genetic.
If it were, then why would two heterosexual people have children who are homosexual (and vice versa)

Homosexuality is a behavior. NOT a learned behavior (like being lazy, or to procrastitnate) but an Innate behavior.

Answer 10

No. Straight people give birth to gay people, and gay people give birth to straight people...so unless it is so deeply ingrained in your DNA that it shows up as rare as natural triplets (w/o fertility drugs), then it is not genetic.

EDIT - But that doesn't mean that it is a choice either.
