Discover the answers to your family history mysteries using the most-cutting edge tool available. This plain-English guide is a one-stop resource for genealogy DNA testing. Inside, you’ll learn what DNA tests are available: the pros and cons of the three major testing companies; and advice on choosing the right test to answer your specific genealogy questions. Once you’ve taken a DNA test, this guide will demystify and explain how to interpret DNA test results, including how to understand ethnicity estimates and haplogroup designations, navigate suggested cousin matches, and use third-party tools like GEDmatch to further analyze your data. To give you a comprehensive view of genetic testing for ancestry, the book also discusses the ethics and future of genetic genealogy, as well as how adoptees and others who know little about their ancestry can especially benefit from DNA testing. Whether you’ve just heard of DNA testing or you’ve tested at all three major companies, this guide will give you the tools you need to unpuzzle your DNA and discover what it can tell you about your family tree.
