Bisexual Men Have Female Relatives to Thank

Tip of the Hat to MR for the pointer.
There's a new study out on different sexual orientation. The New Scientist says:
"Bisexual men might have their "hyper-heterosexual" female relatives to thank for their orientation.

Previous work has suggested that genes influencing sexual orientation in men also make women more likely to reproduce. Andrea Camperio Ciani and colleagues at the University of Padua, Italy, showed that the female relatives of homosexual men tend to have more children, suggesting that genes on the X chromosome are responsible. Now the team have shown that the same is true for bisexuality."
