Gender Differences
Gender differences are variances between males and females that are based on biological adaptations that are the same for both sexes. This differs from sex differences in that sex differences are driven by actual biological gender disparity (such as distinct physical differences) rather than by differing environmental factors that affect our cognition and behavior. Sex is typically used to mean a biological difference like traits that are sexually dimorphic (different between males and females) whereas gender is more of a range and can include many different attributes because of the social and cultural influences on sexual behavior. Sex differences therefore refer only to those differences that can be attributed solely to biological difference.
