African Ancestry Questions
I have a couple questions about African Ancestry.
How is it that they can feel confident of the tribe if they only check 9 of the markers? It seems odd that with all the movement of people, 9 markers is not reliable enough and therefore is not enough to be certain. Do they return only one tribe or do they indicate 2nd and 3rd possibilities?
As an example, 9 markers on a R1b can provide like marker matches in at least 8 countries.
Also their concentration is very much western African and relatively limited and sparse in the other parts.
