The mechanism of sex/gender differences: From the perspective of behavioral genetics

Abstract

The purposes of this paper are 1) to introduce the methods for determining sex/gender differences from the perspective of behavioral genetics, 2) to review the sex/gender differences in various psychological traits found by these approaches, and 3) to propose directions for psychological gender research using behavioral genetics. While behavioral genetics always focuses on individual gender differences, using sex/gender limitation analysis, such studies can focus on both quantitative and qualitative factors affected by sex/gender differences. By integrated the findings derived from behavioral genetics, gender studies can determine how the environment influences genetic factors, and can describe the developmental trajectories of genetic and environmental factors related to gender.
