The two I've seen pictures of on-line don't appear to have chin clefts. But I'm still curious about the genetics. I couldn't say anything their philtrums (philtra?). They don't seem to be particularly prominent.
But 6 daughters? And all those conflicts with Elijah Muhammad? Where did Malcolm find the time to get a rather dumpy and unprepossessing White high school girl on the other side of the country pregnant with his boy child?
