B) gender similarities are much greater than gender differences.
C) genetic differences between the genders do not contribute to gender differences in behavior.
D) all of these answers are true.

Research has shown that while there may be some differences in behavior between genders, the vast majority of traits, abilities, and interests are similar across genders. Therefore, it is important to remember that gender similarities are much greater than gender differences. Option A is incorrect because there are some gender differences that are found in all cultures, such as the fact that women typically bear children and breastfeed. Option C is incorrect because genetic differences between genders do contribute to gender differences in behavior, but these differences are not the only factor - environmental and social factors also play a role. Option D is incorrect because options A and C are incorrect.
