Dig into the science of how origins DNA evaluates work, their accuracy, and why tracing origins is so complex.

Two sis take the exact same DNA test. The results reveal that one sister is 10% French, the other 0%. Both sisters share the very same 2 moms and dads, and therefore the exact same set of forefathers. So how can one be 10% more French than the other? Tests like these count on our DNA to address concerns about our ancestry, but DNA in fact can’t tell us whatever. Prosanta Chakrabarty explores the accuracy of DNA tests.
