The Real Story on Gay Genes

Summary:

This article is basically about different universities and individuals that are researching homosexuality and the theories that they have proposed. The issue of homosexuality is highly controversial. Some people believe that homosexuality is a result of a personal choice or environmental and social background. Others believe that it is genetic. Many people from either side of the spectrum have begun researching this issue. They have come up with many theories including the following.
Theories:
1. A geneticist named Dean Hamer claimed to prove that homosexuality is genetic. He said that it is passed on by the X chromosome from the mother. He said that a piece of DNA called Xp28 has something to do with homosexual tendencies because it showed up in men who claimed to be gay.
2. William Reiner studied whether or not the environment and social upbringing of a child has any influence on sexuality. His studies showed that males that were raised as females were still attracted to women. This article says that if social upbringing did influence sexuality, then some of these males would have ended up attracted to men.
3. Sven Bocklandt is a geneticist at the David Geffen School of Medicine at UCLA. In his study, he gathered DNA from two groups of fifteen pairs of identical twins. In the first group the the twins were both gay and in the second group one twin was and the wasn't. Identical twins have the same DNA, but there is something called Methylation that determines which inherited genes will be "turned on". Supposedly this methylation can be changed and affected by outward influences such as environment or diet. He says that methylation could prove why one identical twin could be gay, while the other one wasn't. Bocklandt believes that if homosexuality is genetic, that there will not be just one "gay gene" but multiple ones because of the complexity of the human body.
4. Alan Sanders is an associate professor of psychiatry at Northwestern University. He said that the biggest problem with homosexuality is that it goes against the idea of evolution of the human race. He says that if human kind is meant to reproduce, then homosexuality only hinders that. His theory, in light of this, is that the gene that makes men attracted to men can also be found in women. When found in women it does not make them attracted to women, it just makes them even more attracted to men.
5. Simon LeVay and William Byne both conducted separate studies that claimed that there is a part of the anterior hypothalamus called INAH-3, that is smaller in gay men. They said that the size of the INAH-3 in gay men was about the same size as women's.


Opinion:
I think that it's a little ridiculous that this article is titled "The Real Story on Gay Genes", since this article just proves that no one has come to any conclusion on the subject. The whole article seemed purposely vague. All these theories didn't have any real evidence for what they stated, at least not any shown in this article. I think a lot of the theories completely contradict themselves as well. Reiner's study said that children could not be influenced by the environment to be gay, but then Bocklandt claimed that methylation, which had to do with homosexual tendencies, could be affected by the environment. What?? This article just sounds like just a wild bunch of ideas to defend these people's view of homosexuality. The article claimed it was non-biased, but if this were so, why didn't the article just admit the fact that they (obviously) can not prove that it's genetic?
