IS THIS HOW HOMOSEXUALY EVOLVED? GEN LKED TO SAME-SEX SEXUAL BEHAVUR ARE ALSO FOUND STRAIGHT PEOPLE AND E THEM TO HAVE MORE PARTNERS - OUTWEIGHG THE 'LOSS' OF REPRODUCTN AMONG GAY PEOPLE, STUDY CLAIMS

THE SHOCKG WAY NEWSPAPERS WROTE ABOUT THE NOW-BUNKED ‘GAY GENE’ 1993

THERE IS NO SINGLE 'GAY GENE'Scientists have long sought to quantify the extent to which geic and non-geic (or environmental) factors impact a person's preference for same-sex relatnships.

Var studi have hted that geic factors were plex, but their relatively small sl ma hard to draw reliable one study, rearchers ed data om over 470, 000 people, over a 100 tim more than prev nfirmed that homosexualy stems om both environmental and geic than their beg one sgle 'gay gene', however, the team found thoands of plac — or loci — the genome that seem to play a role five of the had a 'signifint' impact — and, bed, all the factors acunted for only 8–25% of the variatn sexual attractn between different factors at play are so plex that is impossible to predict om a person's DNA whether they are attracted to members of the same-sex or not.

Preference for same-sex relatnships is termed by both environmental and assorted geic factors, a large-sle study has means that there is no such thg as a sgle 'gay gene' that term your sexual preferenc — jt like many other human tras.
