Final answer:
The correct statement is that there are more similarities between males and females than there are differences. Cognitive and behavioral differences are minimal, and many perceived differences result from cultural rather than biological factors.
Step-by-step explanation:
The statement about gender differences that is true is C) There are more similarities between males and females than there are differences between them. Research, such as that reviewed by Anne Fausto-Sterling, has shown that cognitive and behavioral sex/gender differences in humans are often minimal, with no statistically significant difference found in the majority of studies. Where differences in skills such as verbal and spatial abilities exist, they tend to be very small. Moreover, many perceived differences may arise from social and cultural factors rather than biology.
This aligns with findings from anthropology and biology that emphasize that while there are biological sex differences, the characteristics associated with gender can vary significantly between different human societies. Gender roles and expressions are culturally constructed and are subject to great diversity and flexibility. So, the small differences that do exist between males and females are often overshadowed by the similarities and the individual variations within each gender.
