Why Gays Don't Go Extinct

Homosexuality in males may be caused in part by genes that can increase fertility in females, according to a new study.

The findings may help solve the puzzle of why, if homosexuality is hereditary, it hasn't already disappeared from the gene pool, since gay people are less likely to reproduce than heterosexuals.

A team of researchers found that some female relatives of gay men tend to have more children than average. The scientists used a computer model to explain how two genes passed on through the maternal line could produce this effect.

Camperio-Ciani and his team hypothesize that the genes they modeled may cause people of both sexes to be extremely attracted to men, which would lead men with the genes to pursue relationships with other men, while causing women with the genes to have more sexual partners, and become pregnant slightly more often than an average woman.
