Reconstructing Your Genetic Family Tree


15,148 views

A genetic family tree is the list of genealogical ancestors from whom you inherited DNA. One of the goals of genetic genealogy is to recreate this genetic family tree through a process called “chromosome mapping.” Chromosome mapping uses cousin matches to identify which segments of DNA came from which ancestors, thus recreating your genetic family tree. We’ll look at the fundamentals of chromosome mapping and some tools you can use to begin to map your DNA.
