Why Gays Don’t Go Extinct

I recently found this article…

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.

In 2004 the researchers studied about 200 Italian families and found that the mothers, maternal aunts and maternal grandmothers of gay men are more fecund, or fruitful, than average. Recently, they tried to explain their findings with a number of genetic models, and found one that fit the bill.

If this scenario turns out to be true, it could help explain the seeming paradox of hereditary homosexuality. Since gay people are less likely to reproduce than heterosexuals, many experts have wondered why, if homosexuality is caused by genetic factors, it wouldn’t have been eliminated from the gene pool already.

But if the same genes create both homosexuality in men and increased fertility in women, then any losses in offspring that come about from the males would be made up for by the females of the family.

?”, I think it is only proportional to the growing world population.
