homosexuality begins in genetics or heredity?

Answer 1

Homosexuality has been shown to have a genetic basis, but the occurrence appears to be a random occurrence and not based on heredity (just as left-handedness is not a hereditary feature).

Answer 2

Your statement proves that sexual orientation is not a learned behaviour. Both of the twins were obviously raised together in the same familial, cultural, and societal environment. Obviously they have shared many of the same experiences in life. Obviously identical twins are not always absolutely 100% identical. Perhaps sexual orientation can be understood as a subtle difference in the anatomy of the human brain. Consider that homosexuality occurs in about 10% of the human population. That means that there is some sort of minute cellular mutation or difference in areas of the brain responsible for sexuality and sexual orientation in those individuals compared to the other 90% of the human population. In this case, different means different, not better or worse. You know, I find it curious that you can make statements about the nature of sexual orientation by bringing up the identical twin issue and then you don't want to acknowledge science as having a possible explanation for the differences between heterosexual and homosexual persons. If you can't accept theories for what they are, possible explanations, then what do you accept as proof? Moral Judgements, Religious Dogma or Philosophical Codes? Those aren't valid forms of evidence, either. In fact, I really doubt that your identical twin scenario is a valid statement either, because you weren't able to observe the identical twins from their birth to the state they are in now. You are only stating the obvious, the things that you and everybody else can see, but you can't understand why the twins experience life the way they do each in their own way. You ask for my view...I think that there is a scientific explanation for the existence of differences in sexual orientation...but I think it's going to very difficult and time consuming and resource intensive to get to the exact reason why the differences occur. I think that investigating the issue might turn out to be a waste of time and effort, and since that issue seems to be relatively less important than others, the answers may never be fully known or understood unless some researcher stumbles onto them while looking at something else.

Answer 3

As far as I know, scientists have never been able to prove or disprove that theory. It is my unprofessional opinion that it does begin with heredity, b/c people always seem to have strong attractions towards one sex or the other, and they can't control it no matter what mental processes they go through, so I would think it is. But like I said, not even scientists have been able to prove that sexuality is either mental or genetic, so as for right now, no one knows the real answer.

Answer 4

I don't know about genetics, but we do know that it begins in the womb as part of the mothers immune system response to having had too many male infants inside her. Part of her immune system "remembers" each male infant and the number that's she carried and responds as if it is somehow a defect. Look this up, it has been researched extensively and is the Theory that the "more brothers you have, the more likely you will be a gay sibling." I have 5 brothers, I'm the youngest and I'm gay, 'nuff said.

No matter how people feel about the issue, it is increasingly hard to argue that genes play no role in homosexuality. The evidence began to pile up in 1991, when studies showed that identical twins were more likely to have the same sexual orientation than other pairs of siblings. That same year, a California scientist reported slight brain differences between gay and straight men, although the conclusion is disputed. And in 1993, an NIH researcher found a stretch of DNA on the X chromosome that seemed to harbor one or more genes affecting sexual orientation. But no one has proved that a particular gene promotes gayness or has offered any convincing theory of how genes could influence a person's choice of sleeping partners.

The last male child in a family of many boys is likely to be gay, Canadian researchers find.

A study, published today in the US Proceedings of the National Academy of Sciences online journal said "the most consistent bio-demographic correlate of sexual orientation in men is the number of older brothers (one has)" and not social influences.

Answer 5

I would say that it is genetics, not heredity. it's a genetic variation, like have blue eyes or brown eyes. as I know of no one else in my family that is gay or lesbian, I don't think I would say it's heredity.

Answer 6

Um, genetics are hereditary, so I guess both. If you mean learned behavior or genetic, you have to consider that the accepted psychological theory of learning states that we do things because we are rewarded for them. Being gay is seen very negativly, and those who are gay are almost always punished for it, thus it fails to fit the criteria to be learned.

Answer 7

HUH?????--genetics and heredity are the same thing.

Answer 8

genes...one's heredity...do you mean preference or genetic? i just realize its my preference but don't kno if i'm wired like that.

Answer 9

neither it begins in the choice of the individual

Answer 10

Neither, its a habit to which you get accustomed.
