Research Conclusion: No Gay Gene

More than once, claims have been made that there is a genetic basis for homosexuality. A new study to be published in the March 2005 issue of Human Genetics, available online now, underminds this commonly held view, despite the author's best efforts to do otherwise.

In a press release from University of Illinois at Chicago, the study’s lead author Brian Mustanski said, "There is no one 'gay' gene. Sexual orientation is a complex trait, so it's not surprising that we found several DNA regions involved in its expression." However, a thorough examination of the actual report reveals no statistically significant findings for any of these DNA regions.
