Is Being Gay Hereditary/Genetic?

[Paluka]

[ QUOTE ]

All gay persons parents, grandparents and their entire ancestral lineage engaged in heterosexual sex. How could being gay be a genetic trait?

[/ QUOTE ]

I'm pretty sure plenty of homosexuals have engaged in heterosexual sex.

Andy: Hold on, his daughter? But he's definitely gay.

Maggie: He can't be gay if he's got a daughter.

Andy: Oscar Wilde was married with two kids.

Maggie: Well he can't have been gay.

Andy: What Oscar Wilde?

Maggie: Yeah.

Andy: Got to stop hanging around with you.

i was waiting for someone to say that.

i do think there are some hereditary aspects of homosexuality. i have no evidence to back this up other than examples i have seen, but i know so many sets of identical twins who are both gay (and i cannot think of any where one is and one isn't). personally, my parents were both gay (but didn't individually realize it until long after they'd had me and my brother) and i am as well. i dont know what's going on with the bro but in any case i can point to so many families with gay parents and gay children. can this really be merely a coincidence? (and i dont believe for a second that if you grow up around gay parents you will "learn" to be gay)

Sample size blah blah [img]/images/graemlins/tongue.gif[/img]

Just kidding. Sorry, I work as a genetic data analyst so I had to throw that at you.

[mgsimpleton]

lol sample size is why i claim i basically only have anecdotal evidence. but it would be one hell of a coincidence because i know too many examples not to be somewhat convinced.

I think some biologists have found genes which show a propensity for homosexuality. It is most certainly not entirely based on environmental factors, nor is it entirely genetic.

Are there any animals known to be gay? Like prefer gay sex over hetero sex? I know some animals such as Rams and Wolves mount each other, but that can be explained with social status and stuff. Alpha male exerting his dominance and all that jazz.

Chimpanzees (especially bonobos) have gay sex all the time (and I do mean all the time).

I think they're all bi though; as far as I know, no one's observed a strictly homosexual bonobo. They're just too horny to limit themselves to just one gender.
