‘Once you make a decision, the universe conspires to make it happen.’ –R. W. Emerson
It is well recognized that there are consistent differences in the psychological characteristics of boys and girls; for example, boys engage in more ‘rough and tumble’ play than girls do.
Studies also show that children who become gay or lesbian adults differ in such traits from those who become heterosexual – so-called gender nonconformity. Research which follows these children to adulthood shows that between 50 to 80 per cent of gender nonconforming boys become gay, and about one third of such girls become lesbian. (…)
The team followed a group of 4,000 British women who were one of a pair of twins. They were asked questions about their sexual attractions and behavior, and a series of follow up questions about their gender nonconformity. In line with previous research, the team found modest genetic influences on sexual orientation (25 per cent) and childhood gender nonconformity (31 per cent).
