With 23andMe becoming more and more talked about, some people have wondered if there is such a thing as a gene that makes someone gay. Based on all the data collected, it is impossible to determine if someone is gay based off of genetics. Sexual preference is similar to food preference, how could we collect someones DNA and know if they prefer apples over oranges? Exactly, we can not. This was a very thorough investigation and there was no evidence that could back up the gay gene theory. 23andMe is a scam considering they say they can analyze someone's DNA and determine if they are gay, but for a price of course. A researcher said it is more likely to be an element of the environment, but not disregarding the fact that someone does not choose to be gay, but it is simply how one feels.
In my opinion, I do not believe genetics is a major contribution to sexual orientation. We are a complex species and one can not help who are what they are attracted to. For someone to say being gay is a choice is the same thing as saying being straight is a choice. We can not help who we are, only the decisions we make. I also think it is unfair how 23andMe is taking advantage of people by saying they can provide answers when they are just providing false claims and making money.
