Mother's Gene may be Behind Male Homosexuality | |

Contrary to the belief that homosexuality as a trait would not last long, as it can't lead to procreation, a study has suggested, that 'gay gene' survive through the generations as mothers and maternal aunts of gays tend to have significantly more kids than the relatives of straight men.
The study by Andrea Camperio Ciani, from the University of Padova in Italy, spots a correlation between gay men and their mothers and maternal aunt's tendency to have more kids.
They theorise that this leads credence to the 'balancing selection hypothesis', which suggest that a gene that leads to homosexuality also leads to high reproduction among their female relatives.
As such, while the 'gay gene' may not get passed down directly, it will survive through the generations via the family.
The gene or genes, which results into this behaviour, is not yet known, but the report by Ciani suggests that it resides on the X chromosone, of which men inherit one.
Originally, the team considered the hypothesis that the gene would affect men and women in different ways - making the man homosexual, and making females more promiscuous.
However, according to the Huffington Post, after studying 161 females related to both homosexual and homosexual men, they have now arrived to a conclusion that - instead of increasing the woman's promiscuity, the gene makes the women more attractive to men, the Daily Mail reported
'High fecundity, that means having more babies, is not about pleasure in sex, nor is it about promiscuity," the Daily Mail quoted Ciani as telling Life's Little Mysteries.
'The androphilic pattern that we found is about females who increase their reproductive value to attract the best males.'
He claimed that the gene led to women who were more fertile, displayed fewer gynecological disorders, and less complications during pregnancy.
They also tended to be more extrovert, happier and more relaxed.
The study will be published in the Journal of Sexual Medicine.
