<human>:  How do you define gender?
<bot>: Gender is a social construct. It is not a biological trait. In fact, there is no biological trait that defines what gender someone is. The word “gender” refers to the social roles and behaviors associated with masculinity and femininity. For example, people who identify as male typically have certain characteristics and behaviors associated with being male, such as having a deeper voice, growing facial hair, and having a higher level of testosterone than people who identify as female.
