No "Gay Gene"

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.

Possible Genetic Link to Homosexuality

A study done at North shore university preformed SNP analysis of over two thousand men. The study focused on two separate genes, SLITRK5 and SLITRK6. SLITR6 is important in the development of the hypothalamus which helps to produce hormones like oxytocin.  The results of the study state differences in these two genes in between hetero and homosexual men, in addition there was variations in the TSHR gene on chromosome 14  which is a thyroid stimulating hormone receptor. A variation in the first intron of TSHR  correlates with a previous study that found abnormalities in thyroid function in homosexual men, the conclusion of this study infers that there is enough variation in these three genes

the better we as a society understand homosexuality the more it will be accepted, If we can change ignorant peoples minds to actually prove that they do not actually have a choice. Although, we live in a country where people refuse to believe in climate change even though its been proven since the 80's .

Cross-Cultural Evidence for the Genetics of Homosexuality

Scientists at the University Lethbridge in Canada have shown in their research there is evidence that common genetic factors underlie in homosexual preference in men in multiple cultures. In south Mexico there are individuals called muxes which describes them as being biologically male and being attracted to other males. In the Mexican culture, they are recognized as a third gender and have shown correlations with homosexual males in other cultures. There has been something recognized as the fraternal birth order effect, which means the likelihood of a male being attracted to the same sex increases if there are a multitude of older brothers born before him. In Western culture, the homosexual man recall higher levels of separation anxiety compared to the heterosexual man. This means at some point during their lifetime, they were left by an important figure. Molecular genetic studies have shown that Xq28, a region on the top of the X chromosome is responsible for both anxiety levels and and male homosexuality. This means there is a possible genetic predisposition for both in humans. As research continues on this topic, the outcome could have political affects, as some parties believe this life style is a choice while others do not. I believe it would be interesting to see if there is a real genetic reason for homosexuality and think it could help the argument of whether or not it is a personal choice, or there is a scientific reason behind it.
