They’re called “mulatto”. The average black person in America is something like 25% white... which is why our blacks are significantly more intelligent than the ones in Africa.
I thought that the word “mulatto” fell out of favor long ago.
My great-grandmother passed herself off as part Native American; she even raised my grandfather in Indian territory. I suspect that she was actually mulatto, since our DNA analysis showed no Native ancestry, but there is some African ancestry.
