    Scientific researchers specializing in human sexuality have shown that homosexuality is genetic.

    Scientific research publications from October 2004 and June 2008 have both stated that scientists have found that women tend to have more children when they inherit the same genetic factors linked to homosexuality in men. This fertility boost more than compensates for the lack of offspring fathered by gay men, and keeps the “gay” genetic factors in circulation.

    A 2005 study reported genetic scans showing a clustering of the same genetic pattern among gay men on three chromosomes - chromosomes 7, 8, and 10. The regions on chromosome 7 and 8 were associated with male sexual orientation regardless of whether the man got them from his mother or father. The regions on chromosome 10 were only associated with male sexual orientation if they were inherited from the mother.

    A study from 2006 said that researchers have known for years that a man's likelihood of being gay rises with the number of older biological brothers, but the new study found that the so-called "fraternal birth order effect" persists even if gay men were raised away from their biological families & that "the research suggests that the development of sexual orientation is influenced before birth."
