There are many suspected influences of homosexuality in humans. Some believe that sexual orientation is socially influenced and some believe that it is a choice to be homosexual. In a new study it is suggested that it is influenced by genetic information. This study was led by Alan Sanders and it is the largest of its kind.
Over 400 pairs of gay brothers, some twins, participated in a genetic analysis that focused on two region of the human genome. Samples of blood and saliva were collected from each of the participants. The only trait that all 818 men shared was being gay. Two genes were identified in influencing sexual orientation in men. One of the genes is located on the X chromosome, which is one of the chromosomes responsible for determining a person’s sex. The other gene that was found to correspond to sexual orientation in men was found on chromosome 8.
The goals of this study were to contradict the notion that homosexuality is a choice and to “refute” the belief that gay people can be treated to be straight. It was stressed that sexual orientation is determined by numerous different factors from the environment to genes. There is not one reason for homosexuality.
