Autosomal DNA is the most popular DNA used in genealogy. In this presentation, I plan to describe both the biological and genealogical traits of autosomal DNA, then to show both the value and limitations of tools that can be used, such as Ancestry thrulines and Family Tree DNA (FTDNA) chromosome browser. A case study of my NH Graham family will be used to demonstrate these principles.
