X-DNA, one of the sex chromosomes, is an often-overlooked feature of DNA testing. We will explore how evaluating matches on the X chromosome can enhance genealogical research, where X matching is available, the unique X-DNA inheritance patterns, and tools that can help to evaluate connections. In this presentation, Pam explores the uses of some of the newer tools at Ancestry, and compares them with FTDNA and MyHeritage tools. Her goal is providing researchers with new ideas for using DNA– and knowing what sites to use.
