I recently served as a faculty expert an article that the California State University system wrote about those popular direct-to-consumer DNA tests for family history.
Yesterday I launched my newest research guide, on using DNA for genealogical research — a focus of much of my own research time and dime this year. The research guide is by no means complete. I am still scrambling to add more material, and will continue to regularly update it. It is meant to be comprehensive, but not exhaustive. Includes a special getting started section for beginners.
