Sex and Gender: Sex refers to the biological characteristics that categorize someone as either female or male; Gender refers to the socially determined ideas, roles and practices of what is expected of male or female. These ideas and roles are assigned by cultural beliefs of a community. Culture: This is distinctive patterns of ideas, beliefs, and norms which characterize the way of life and relations of society. We already said that culture defines the roles of men and women. This brings about gender stereotypes. For example we normally assume that women cannot be leaders or cannot initiate development for the family, only men can. This is a stereotype because there are many cases where women are actually the breadwinners of their families. Men cannot be good in child caring, another stereotype which prevents men from childcare duties even if they might be good at it. Another way to understand these concepts is to know the meaning of patriarchy; systemic societal structures that institutionalize male physical, social and economic power over women. That is why it is important to understand the concept of power relations; the hierarchical power between men and women that tend to disadvantage women.
