The “Gay Gene” is Proven in New Study

Two spots on the X chromosome makes about 40% of the decision if a person will be gay or straight according to a new study in the Washington Post:

Researchers at the Human Genome Project, an international scientific research group that examines human DNA, conducted a study on several pairs of gay brothers.


“Sexual orientation has nothing to do with choice,” Michael Bailey of Northwestern University, who carried out the research, said. “Our findings suggest there may be genes at play, and we found evidence for two sets that affect whether a man is gay or straight.”


The study drew blood from 409 gay brothers and their heterosexual family members. Analysis confirmed that an area on the X chromosome does, indeed, have some impact on sexual orientation. It also confirmed another stretch of DNA on chromosome 8, which affects male sexual behavior.

Do you think the findings are true?
