Homosexuality's "X" factor.
The findings, released February 21, found that almost a quarter of mothers with more than one gay son in the study processed their X chromosomes in the same way. The research "confirms that there is a strong genetic basis for sexual orientation and that for some gay men, genes on the X chromosome are involved," study coauthor Sven Bocklandt, a postdoctoral researcher at the University of California, Los Angeles, told the HealthDay Reporter.
But lonel Sandovici, MD, a genetics researcher at the Babraham Institute in Cambridge, England, was skeptical. The study was small, he said, and most of the mothers of multiple gay sons didn't share the unusual X-chromosome trait. The origins of sexual orientation remain "rather a complicated biological puzzle," Sandovici said in HealthDay Reporter.
