This is Part 1 of 2 specifically the Big Y-700 DNA test. It is a subject that is not easy to learn about. Once you get your results you still need help to determine how you can use it to get the most information about your genealogy. It is a tool that does not work by itself, but needs a team effort of testers. Dr. Lee Martinez takes you step by step using his ancestors and team of people that he matches. There is so much new technical terms that you have to watch it more than once to understand it.
