Direct-to-consumer genetic testing is a booming industry. Providers claim that their tests can reveal critical information about your health and ancestry. But how reliable are those claims? In this public presentation, Dr. Ryan Gutenkunst discusses the science behind the hype. He addresses what these companies are actually measuring when you send in a sample and how they use those measurements to learn about your past ancestors and your future health. Dr. Gutenkunst shows us how the complexities of human biology and human history limit what can be learned from genomic tests.
