Though not everyone classifies them the same way, generally speaking there are about ten genetic clusters for humans. One is abos, eight are various groups in Africa, and the last one is the rest of humanity. Pretty much all humans are relatively closely related except abos and Africans, who are their own things, and in the case of Africans, a bunch of different groups within. Japs, beaners, chinks, wops, micks, etc. are all small variations compared the all the mystery DNA that's floating around in Africans. Abos might as well be from Mars.
