Answer: The answer is race.

Race is a category of people who share inherited physical characteristics and are seen as being a distinct group.

Explanation:

Race refers to group of people with different similarities in biological traits viewed as distinct by the society. It also mean an individual's identification with one or more social groups. Individuals treat other people differently because of physical and social qualities. Some of these qualities include skin colour, hair colour, eye colour and so on.

I believe that would be a "RACE" of people. Such as white, hispanic, native americans, etc.
