New Evidence Shows that Genetics Influence Sexuality

A new study that involved 800 homosexual brothers and twins has shown that 2 genes are linked to male sexuality.  One of these genes is on the X chromosome while the other is on a different chromosome.  While this does not give definitive proof that sexuality is determined by genetics, it brings many people one step closer to the accepting the idea that sexuality is not a choice.  For a long time, people have debated the idea of nature vs. nurture; which one determines sexuality? Many people believe that being gay is a choice or that the environment influences sexuality.  This study has brought forward evidence that sexuality is determined by genetics, just like hair color.  It is a possibility that the environment influences sexuality when a person has a genetic predisposition for a certain sexuality.

I think it is morally wrong to believe that sexuality is a "choice" and that a person has chosen to be attracted to men, women, or both.  This study gives more evidence that people do not have a choice in their sexuality and who they are attracted to.
