Circles or Triangles? What Shape is Your DNA?


As we march forward into another year of genetic genealogy much is being discovered about the ways in which we can analyze our autosomal DNA data. There is a hot debate over two seemingly competing ideas: the DNA Circle, or the Triangulation method. The DNA Circle was pioneered by AncestryDNA and relies on small shared segments and complete family trees. The Triangulation method requires a chromosome browser and detailed calculations of shared amounts of DNA. We will cover questions like, Which is the best route to take? Do I need a chromosome browser? How can I use these methods in my own genealogy? Autosomal DNA is an ever changing field, this lecture will cover the latest methods of analysis and interpretation for the non-scientist genetic genealogist.
