I recently had a genetic analysis done to determine my ancestry - courtesy Ancestry24, theMedical Research Council, the National Health Laboratory Services and WITS University. It was a free test, and it came with an informative booklet to explain the results.

Through the African Institute for Mathematical Sciences I was given an opportunity to participate in a free Genealogical DNA test to trace my ancestry. They can do two tests for men, and one test for women. The tests trace you back through your mothers-mothers-mother or your fathers-fathers-father to the most recent ancestor with a non-coding DNA mutation.
