A lot of people are going to be surprised.
A LOT of American blacks are going to be surprised to find the're 25%, 50% or even more than 50% "European."
And a good number of American whites, particularly in the south, are going to find there's a Black African or two in their ancestral mix in the last 200 years or so.
I have a photograph of my great great grandmother. She's very dark -- turns out she's not AA but NA -- Native American. And I've got green eyes and light brown hair. And I burn in the sun -- so that Indian blood hasn't done me much good in the sun tan department. LOL
On the other hand, 1/16 of something doesn't have much effect.
