The study will not be the last word on the vexg qutn of what homosexualy, however. Natnal Cancer Instute and his lleagu published a paper suggtg that an area on the X chromosome lled Xq28 uld nta a “gay gene.

His study, which analysed the genom of 40 pairs of gay brothers, looked exclively at people who intified as homosexual.

To evolutnary blogists, the geics of homosexualy seems like a paradox. In theory, humans and other animals who are exclively attracted to others of the same sex should be unlikely to produce many blogil children, so any gen that predispose people to homosexualy would rarely be passed on to future generatns. Yet same-sex attractn is wispread humans, and rearch suggts that is partly geic.In a study of data om hundreds of thoands of people, rearchers have now intified geic patterns that uld be associated wh homosexual behavur, and showed how the might also help people to fd different-sex mat, and reproduce.
