Homosexuality & Genetics?
ByQuestion by eSkye: Homosexuality & Genetics?
I’m asking this as an out lesbian.
I am currently taking AP Psychology and am reading the section about sexuality and genetics. I’m finding it incredibly interesting. Here are my findings:
There are many animals that are naturally homosexual. There has been studies that show you can make a rat homosexual by injecting it with certain hormones, as well as fruit flies. Dolphins, goats, fruit bats, penguins, and orcas are all animals that commonly exhibit homosexual tendencies,
As well as that, studies of humans show that homosexuality lies in the structure of your brain. Straight men have larger hypothalimic brain clusters than women and gay men. Scientist Simon LeVay comments on this finding with “Gay men simple don’t have the brain cells to be attracted to women.” The Anterior Commisure is also larger in gay men than straight men.
These brain differences are accompanied by genetic differences. There are correlations between the differences of spatial abilities, fingerprint ridge counts, auditory system development, handedness, occupational preferences, relative finger lengths, gender noncomformity, age of onset of puberty, male body size, and sleep length and of sexual orientation.
The scientist Glenn Wilsion said “Modern scientific research indicates that sexual orientation is partly determined by genetics, but more specifically by hormonal activity in the womb.”
Studies indicate that male homosexuality is more likely to be transmitted from the mother’s side of the family.
So, homosexuality is not unnatural by any means. It is proven to be just another genetic difference, such as hair or eye color.
I think these things should be more widely known. Just saying “Love is love” is no solid evidence to an ant-gay. At least, to me it isn’t. I don’t feel that I need to justify my sexuality, but I do like to know that there really is something natural and unchangable about it.
What do people think of this? Do you find that it interferes with the idea that “Love is love, no matter what”? Do people find it sickening that we have to back up our “ways” with scientific evidence?
There is no “gay” gene that has yet been identified, so no, it cannot be turned on and off.
Also, since the orientation is correlated (I do NOT mean caused or causing) with cognitive differences and even bodily differences, there is no way you can just “turn it off” or “recover from it”. You can’t change your fingerprint. Fingerprint differentiations are correlated with sexuality. You can’t get rid of it,

MANY MANY species of animals have homosexual, bisexual, and heterosexual members.
Anyone that doesn’t keep up with the science is willfully blinding themselves to the truth.

We choose to feel the way we do and choose to be the way we do.
It depends on food we eat, lifestyle, pshycological, mentallity etc. Its a test. Test to see what path we choose. Just like a test to see if one chooses to do drugs and be an addict or not.

My research has been far less in-depth than what you’ve looked into, but I’ve been finding that it’s a mixture of genetics and influence. Recent studies have shown that some genes can be turned on and off, so to speak. So basically, the ‘gay gene’ can be turned on depending on environment and influence.

My personal thought: I’m beyond sick and tired of proving my existence to breeders.
You are right though, some of them are smart and need more of a simplistic answer then “love is love”, I just don’t see why I should bother. After all, who knows better about being gay us gays or the breeders who so love to condemn us.
