I bet nobody told junior that part.
Speaking of DNA tests for this, I thought it only traced the paternal side, but this article said maternal/Ibo.
Hey genius,
You can ONLY do an historical genetic tracing through the maternal genes (has something to do with RNA I believe). Remember that womens have only 1 Y chromosome, while men have 2. Maternal tracing allows you to back-track through that one 1 chromosome (which will also be in her mother and her grandmother and her great grandmother and so on and so on and....)
If you tried to do this through a paternal line, you could only trace back to the father (then you'd have to figure out which of the two grandfathers and then the potential 4 great grandfathers and then the potential 16 great-grandfathers and so on and so on and....)
