Michelle Bray Wilson – DNA Doubleheader: The Structure of DNA and the Commercially Available Kits.
Presentation Description:
The Structure of DNA and the Commercially Available Kits. Learn the organization of DNA as applicable to the genealogist, how it varies from person to person, and what the various types of tests actually examine and report on. We’ll cover everything from the old-style paternity and “CODIS” tests, to the Y-DNA STR and SNP tests (and how these differ from haplogroup reporting), mt-DNA tracing back female lines, and the popular autosomal tests offered at the “big four”, 23andMe, MyHeritage and FamilyTreeDNA. Along the way, we’ll discuss Best Practices (part 1) including which test company to choose for candidate testees, what to expect when your results arrive, and a couple of third-party tools where you can do even more.
