Thesis: There is more than one factor in influencing sexual orientation, of which seem to be environment and genetics.
Many people believe that homosexuality is unnatural and should be prevented. Some even think it is a disorder that can be ‘cured’. There is much evidence that homosexuality is a result of genetics. One study found that those who were homosexual had more aunts than those who were heterosexual. Although this does not say much about predicting homosexuality or the likelihood of having a homosexual son or daughter, it does prove that there is some sort of genetic link between homosexuality and genetics.
Another study found that there is a difference between the amount of ___?___ in the brain, resulting in more feminine or more masculine ways of thinking and behaving. This could be why, stereotypically, homosexual men are thought of as acting more “girlie”, and tend to have a lot more female friends than heterosexual men. But although there is significant evidence that homosexuality is linked to genetics through analyzing the amount of ____?____ in the brain. What’s more, I have found that although a person may have the genetics to be gay, he or she may not consider themselves homosexual and may not act or want to act in this way. This would furthermore explain why there are many homosexual men who have very masculine mannerisms, which is generally assumed by many to be contrary be being gay. This observation has therefore led me to believe that there is more than one factor in determining homosexuality.
I have also found that homosexuality is also present in mammals other than human beings, which could support my argument that homosexuality is not a choice.
