According to a new study, homosexuality in males may be caused in part by genes that can increase fertility in females.
Daily Mail has the report:
Researchers believe that male homosexuality may be due to a gene carried by mothers.
Evolution suggests that homosexuality as a trait would not last long, as it discourages sex, with women and therefore procreation.
But a study by Andrea Camperio Ciani, from the University of Padova in Italy, spots a correlation between gay men and their mothers and maternal aunts, who tend to have significantly more children than the relatives of straight men.
They theorise that this leads credence to the ‘balancing selection hypothesis’, which suggest that a gene which 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.
