Do you believe that you are supposed to act certain ways and do certain things because you are a man or a woman? Gender role is a set of expectations held by society about the ways in which men and women are supposed to behave based on their gender. For example, my wife once told me that I should cut the lawn because that is "the man's job." Although she was kidding (I think) this is an example of an expectation held because of gender. Remember, these are dependent on the culture/society and can change over time.
