Identical Twin Studies Prove Homosexuality is NOT Genetic

heh....why am I not shocked that you accept without question the OP who cites anonymous studies but rejects any that you disagree with?

LOL

 

Now for some real science!

Identical Twins' Genes Are Not Identical
http://www.scientificamerican.com/article.cfm?id=identical-twins-genes-are-not-identical

Geneticist Carl Bruder of the University of Alabama at Birmingham, and his colleagues closely compared the genomes of 19 sets of adult identical twins. In some cases, one twin's DNA differed from the other's at various points on their genomes. At these sites of genetic divergence, one bore a different number of copies of the same gene, a genetic state called copy number variants.

Normally people carry two copies of every gene, one inherited from each parent. "There are, however, regions in the genome that deviate from that two-copy rule, and that's where you have copy number variants," Bruder explains. These regions can carry anywhere from zero to over 14 copies of a gene.

Scientists have long used twins to study the roles of nature and nurture in human genetics and how each affects disease, behavior, and conditions, such as obesity. But Bruder's findings suggest a new way to study the genetic and environmental roots of disease.

For example, one twin in Bruder's study was missing some genes on particular chromosomes that indicated a risk of leukemia, which he indeed suffered. The other twin did not.

The Claim: Identical Twins Have Identical DNA

It is a basic tenet of human biology, taught in grade schools everywhere: Identical twins come from the same fertilized egg and, thus, share identical genetic profiles.

But according to new research, though identical twins share very similar genes, identical they are not. The discovery opens a new understanding of why two people who hail from the same embryo can differ in phenotype, as biologists refer to a person’s physical manifestation.

The new findings appear in the March issue of The American Journal of Human Genetics, in a study conducted by scientists at the University of Alabama at Birmingham and universities in Sweden and the Netherlands. The scientists examined the genes of 10 pairs of monozygotic, or identical, twins, including 9 pairs in which one twin showed signs of dementia or Parkinson’s disease and the other did not.



Conclusion: Identical twins do not have the exact same genes. If Dr. Neil Whitehead had simply searched the internet he would know this. We also know that identical twins don't make the same decisions. If there were wired exactly the same it would be more likely that they would do so, but they don't. There are clearly differences. Identical twins are not exact clones of each other.

For those who still think that homosexuality is a choice, please list all the people of the same sex you want to have sex with (you can be top or bottom, doesn't matter). So far there are 0 on my list. Lots of girls I'd have sex with, like a ton. I see them all the time, especially on the internet. Guys though, haven't found one that gave me some local swelling. If it's a choice then how do I choose to become attracted to men? I mean it seems like watching TV, drinking beers, and (*)(*)(*)(*)ing your buddies would be a hell of a lot easier than dealing with women, yet for some reason the thought of having sex or even making out with another man disgusts me and makes me feel sick. I don't get that feeling with thinking about women. Maybe there's something wrong with my genes.

 

How do you know that no one is born hetero?

 

WHy are you and FingID so desperate to believe that homosexuality isn't a choice?

You not only don't believe it isn't a choice, you don't WANT to believe it is a choice. Why not? What difference does it make to you?

I believe that homosexuality is a choice. I feel very confident. But if I were to find out for a FACT that it is not a choice, I wouldn't care. I'd probably be glad to know, actually.

But you guys DO care. Why? It doesn't matter which it is, as long as we find out the truth, right?

And sorry, boys, but the way you guys fight for it, it's fairly obvious that you CARE. Not 100% certain I admit, but it's pretty close.

 

Okay- I don't know whether you are heterosexual or homosexual, but I am heterosexual.

I never 'chose' to be heterosexual- I have always been attracted to girls/women and never to boys/girls. NEVER.

Every gay man I have ever known has told me that his experiences were exactly the same. This repeats itself with every adult I have ever had this conversation with.

So- what about you? When do you believe you chose to be whatever sexual orientation you have?

Oh and one more thing- frankly I think this argument about whether someone is born homosexual or heterosexual is rather insulting as other than a scientific argument. I don't think anyone has to justify who they are attracted to to me at all.

 

I was familiar with both studies before I read about them here. The twin registries are an accurate reflection of the population. Volunteers solicited from gay publications are not.

So what men would you have sex with? I'm just curious because, since it's a choice, you obviously get the same sexual feelings about men that do you about women. I don't because apparently I'm genetically screwed up and don't find men attractive, though I do find women to be. I really didn't know that the rest of humanity simply decides if they are going to be straight or not. It wasn't a choice for me though, apparently I was born straight and I don't see how I could choose to be otherwise.

 

Says the guy with the Bible quote in his signature.

 

It's definitely not a choice because as it always has to be pointed out, no attraction of any kind is ever a choice. So anybody using the choice argument is already positing a faulty premise.

But I think it's important to understand things first rather than just blindly embracing them. Because it's not rational to just accept things without question which could potentially be unhealthy or destructive. Which is why I don't side with the pro-gay side currently. This is and has always been my position on the issue. And it's almost verboten to even look at homosexuality logically because everybody is so eager to polarize it. To either embrace or reject without question in either direction. And that's stupid. How are you supposed to understand something you can't even talk openly about?

This is why the liberal use of words like "hate" and "bigotry" are counter-productive to the discussion. Because they are meant to guilt and shame rather than explain and articulate.

 

Well, i agree to a point, but on the other hand, we can discuss the relative merits of other behaviors without having to first confirm that they are biological. I can like baseball all day long, and no one has ever asked me to justify it, there aren't a ton of threads here or elsewhere asking "Why do you like baseball, is it genetic, prenatal, or a choice". It's only when it's about the naughty bits that anyone cares. I think I would tend to think it's a genetic predisposition possibly compounded by prenatal exposure to industrial chemicals (some of which can mimic human hormones) that make the difference.

My personal thing is that unless we're talking about underage people, your sex life shouldn't actually matter to anyone else. I don't own your junk, you aren't trying have sex with me, so why the heck would a sane grown up think this is a matter for public debate? You like what you like, I like what I like, and so long as everyone consents and is of legal age, I don't see where the public debate comes in.

 

no but as far as I can tell with myself its not even if your bi sexual its not a choice as you don't choose who to be attracted to then either you just have more options

 

why should you not be able to marry someone of the same gender or get benefits from marriage if being gay was a choice?

 

which school taught about man on man anal sex?

ya who done it

 

i don't know of any baby's with a sex drive i figure a lot of them develop heterosexuality as they get older probably do to biology same with being gay but if this twin study s legit then theirs no genetic guarantee of being hetero sexual either

 

If you didn't choose to like baseball but something traumatic happened to you as a child that shaped your identity ever after and subsequently made you a baseball fan, I think society would be doing you a tremendous disservice to just insist that you should be proud of this thing you did not choose. When we are not allowed to discuss where something came from that no one can fully explain, this is the realm we enter into. And it makes the mindless acceptance position not compassionate but extremely hands-off and cold by default. Because it's not even interested in understanding. It replaces curiosity with dogma. And it becomes no different than the argument on the other side that refuses to listen.

If you want my honest opinion, I don't think all cases of homosexuality come from the same source. I think some are probably legitimately inborn. I've heard theories about differences in hormonal development in utero that seem logical. But there are also likely others who were naturally born heterosexual but had their sexual orientation disrupted through childhood trauma. Because trauma victims never have healthy sexuality. And a lot of transgendered people often come from troubled backgrounds.

It's not a compassionate gesture to ignore suppressed suffering because you want to see it as self-expression. If someone is unwilling or unable to differentiate between the two, then they are ultimately harming the other person much more than they are helping them.

 

so is there any trauma that can make some one gay hetero sexual? and do we need reparative therapy's that can turn hetero sexuals who have suffered some trauma back into homosexuals?

 

Who the hell cares? If a man wants to "be with" another man, why should you even care? Does the thought alone make blood rush to your penis? I'll say probably so..

 

you have no idea what you are talking about.

 

actually no there is no legitimate study that says that.

 

I'm not suggesting that we throw parties. I'm not even suggesting it would be wrong to try to change things about yourself you don't like. But on public policy issues, I don't think it's relevant. My theory on those things is "if everyone is of legal age and consents, it's none of our business". I would only have an issue on trying to change things if we're talking about psychoactive drugs on minor children, and that's more about the drug's potential to cause harm than anything else.

 

Not any more than it would make the blood rush to your crack pipe.

 

I would like to know why liberals (especially the gay ones) are obsessed with homosexuality. It could cease to exist for all I care.

 

Maybe not - why is there all this de-gaying through Christian counselling stuff? I wish you were right but I fear you're not.

 

Wassamatterwithit?

 

Being indifferent to someone else's sexuality, provided it's not against the law, is good. I think gay people would be okay with that. It's the interferers that cause concern. And I don't think that liberals/progressives/leftists are obsessed with homosexuality, probably more concerned about inequality, hatred, discrimination and all the rest of it. Heck the Bolsheviks under Lenin probably shot the poor bastards they found so I don't know if it's a political view so much as a humanist view that is being put by contemporary progressives towards the treatment of gay people.
