"which term refers to the belief that members of separate races possess different and unequal traits? "

The answer is "racism".

Racism is the conviction that a specific race is better or mediocre than another, that a man's social and good qualities are foreordained by his or her natural organic attributes. Racial rebellion is the conviction, more often than not founded on prejudice, that distinctive races ought to stay isolated and separated from each other. 

Ithink it’s bill gates.
