Question 1

What have twin studies told us about sexual orientation?

Accepted Answer

Twin studies have provided evidence supporting a genetic influence on sexual orientation, but they also show that environmental influences cannot be ruled out. This suggests that while genetics play a role, there are likely other factors, such as environmental or hormonal influences, that also contribute to sexual orientation.
