Gay men are more likely than lesbians to show gender-nonconforming traits
during childhood, according to a new study by Queen Mary University in
London.
Research following children to adulthood shows that 50%-80% of gender-
nonconforming boys grow up to be gay. Meanwhile, only about one-third of
nonconforming girls become lesbians.
Psychologists Andrea Burri and Qazi Rahman report that genes may be
partially responsible for nonconforming traits as well as sexual orientation.
Burri and Rahman followed a group of 4,000 women who were part of pairs of
twins. After asking about their sexual attractions, behavior, and gender
nonconformity, the team found genetic influences on orientation (25%) and
childhood gender nonconformity (31%).
Ultimately, there is a connection between mental traits and sexual
orientation development.
"There is an association between these psychological traits and sexual
orientation because they all develop under common biological drivers, like
the development of brain regions under the influence of genes and sex
hormones," explained Rahman. |
