In 2011, Lady Gaga sang her song "Born this Way".
This song quickly became a recurring song in gay parades.
Indeed, over the course of two decades, researchers have been able to discover many evidence that homosexuality is not a choice, but it is deeply planted in an individual's biology and is determined by genes.
But so-called "homogeneous genes" are still confusing.
A new study may help us understand this.
The study was conducted on male twins and is scheduled to be presented at the annual meeting of the American Society of Human Genetics (ASHG) in Baltimore, Maryland.
This study found that some changes related to epigenetics may cause chemical changes to the human genome and thus alter the activity of the gene without altering its chemical sequences.
This may cause sexual behavior to change.
In a research paper in 2012, William Rice «William Rice» suggested that these meta tags gene may be the cause of homosexuality while passing from father to daughter, or from mother to son.
Where scientists have argued that the inherited signs may affect the fetus sensitivity to the hormone testosterone, which may be based to "remind" the brains of female (making them more masculine) or the "feminization" of male brains (making them more feminine), which leads to the attraction of the same sex.
Inspired ideas such as those that the survived «Tuck Ngun» study methyl groups in 140 A region of DNA belonging to 37 pairs of twins male matched where one of them was gay and the other altruistic, belongs to 10 other pairs of twins male matched who were all gay.
After repeated analyzes several times, and with the help of an innovative computer algorithm, the team identified five regions of the genome, the addition of methyl groups to them closely related to homosexuality.
One gene was important for neurotransmitters, while another was responsible for immune function.
To test the importance of these five regions, scientists separated the identical twins, one of which was a gay one into two groups.
They then examined the relationships between genetics and sexual behavior in one group.
And then test the way these results predict sexual orientation in the second group.
Scientists were able to reach a 70% accuracy rate.
