'Tomboy gene' linked to promiscuity: More masculine girls 'have more lovers whether they are straight or gay'
Researchers quizzed pairs of twins over sexuality and number of lovers
Found that the genes that control masculinity also control promiscuity
Findings showed 30 per cent of woman's sexuality determined by genes

Genes that make women more masculine also make them more promiscuous, according to researchers from King's College London

Girls who are tomboys grow up to have more lovers whether they are straight or gay, a study has found.
For it seems the genes that make women more masculine may also make them more promiscuous, researchers say.
The finding helps explain why homosexuality doesn’t die out, even though lesbian couples are not able to naturally have children carrying the genes of each partner.
This is because straight tomboys have more lovers than others – and so the ‘tomboy DNA’ stays in circulation, according to the study carried out by a team from King’s College London.
Researchers questioned almost 500 pairs of twins about whether they were attracted to men or women, how many lovers they had had and about their levels of ‘childhood gender non-conformity’ – if they were a tomboy and whether they preferred to play with boys rather than other girls.
They compared the answers from identical twins, who share all their DNA, with those of non-identical twins, who share only half their DNA.
This showed how important genes are compared with other factors that shape behaviour such as friends and education.

The analysis showed that around 30 per cent of a woman’s sexual orientation is governed by her genes, the Journal of Sexual Medicine reports.
It is thought the other 70 per cent can be explained by everything from peer pressure to conditions in the womb.

Scientists compared the genes of identical and non-identical twins, and found that female sexuality is 30 per cent dependent on biology, much more than previously thought
