Quizplus · Accepted Answer

The effect of genes on brain development is the best predictor of sexual orientation. Studies of identical twins have shown that if one twin is homosexual, there is a higher chance that the other twin will also be homosexual, indicating a genetic influence. Brain imaging studies have also shown differences in brain structure and activity between heterosexual and homosexual individuals, suggesting a biological basis for sexual orientation. Factors such as childhood experiences or parenting strategies have not been found to consistently predict sexual orientation.
