The sex of a person, as established by biology, does not necessarily match the individual's gender. As a result, the terms sex and gender cannot be used interchangeably. Because the term sex relates to biological or physical disparities, sex traits will not alter considerably among human civilizations (Griffiths, & Keirns, 2015). Gender characteristics, on the other hand, can vary widely amongst civilizations. The dichotomous perspective of gender (the idea that someone is either male or female) is culturally particular and not universal
