{{Cquote|On July 16, 1993, it was reported in Science (pp. 291, 321) that [[Genetics|geneticist]] Dean Hamer and his team at the [[National Cancer Institute]] had reported on a study involving 40 pairs of brothers both of whom were gay that had led them to conclude that they had discovered a factor on the X [[chromosome]] through which gayness was genetically transmitted to them from their mothers. This was hailed as proof that homosexuality in men is biological in origin. Two years later, however, Eliot Marshall reported in ''Science'' (June 30, 1995, p.268) George Ebers and George Rice of the [[University of Western Ontario]] had unsuccessfully attempted to replicate Hamer's findings and had "found no evidence that gayness is passed from mother to son" genetically. He also reported that the Office of Research Integrity in the Department of Health and Human Services was investigating Hamer's work.<ref>http://www.narth.com/docs/1996papers/silverman.html</ref>}}

In May of 2000, the [[American Psychiatric Association]] issued a fact sheet stating that "..there are no replicated scientific studies supporting a specific biological [[etiology]] for homosexuality."<ref> http://www.cwfa.org/images/content/bornorbred.pdf</ref>
