Sex&Gender

In sociology sex is refers to the physical body part an individual has that separates them from the other. Gender on the other hand is a set of rules and norms that society has pushed upon a certain sex. Sociology helps separate the two, and also points out the differences. For example, when a male baby is born they are usually given boy things to indicate they gender, and girl are usually given pink things to indicate they are females. There things that society have been doing for years, and will be hard to change because society doesn't change easily.
