So where have they all gone? Black descendants of former slaves still live in the US and the West Indies. Whites in the slaving countries of the Middle East, however, not so much. Since they were doing the women, they did not produce white babies. Since the men weren’t getting any, they didn’t produce any babies. In the New World, however, the black slaves were permitted to “jump the broom,” in addition to the prettiest of the girls getting boinked by ol’ massa.
Obviously, a lot of white slave descendants live among Northern Africans and Turks.
Turkish sultans were descendants of many slave women, so they were pretty much European descent.
But, because there is no obvious skin color difference, it is hard to determine who is and who is not.
