A light skinned black person is not always biracial. There are biracial people that are dark skinned too. You cant really tell. One things for sure, black people are multiracial, not biracial. The average Black American will have at least 3 different races in their DNA. Plus biracial shouldn’t exist for black people because no matter the mix, youre still black. At this point youre exotic. An asian woman, normal. Black and asian? She looks exotic. Any race mixed with black is exotic.
