Researchers studied gender dysphoria in monozygotic and dizygotic twins. In this study, all pairs of twins had at least 1 twin with gender dysphoria. Researchers then asked if the other twin also had gender dysphoria.  Assigned sex at birth Twin group # concordant/total # pairs % P value Females Monozygotic 3/8 37.5%   Not done Dizygotic 0/5 0% Males Monozygotic 6/15 40%   Not done Dizygotic 0/16 0% Combined Monozygotic 9/23 39.1%   p = 0.005 Dizygotic 0/21 0% Indicate whether each statement about the table is correct or incorrect: Because monozygotic twins are more likely to both have gender dysphoria it suggests a genetic contribution to gender dysphoria: Because monozygotic twins are not 100% concordant it suggests an environmental contribution to gender dysphoria: Twins assigned male at birth are significantly more likely to be concordant than twins assigned female at birth:
