Descripción editorial
Written by two of the country's top genealogists, this is the first book to explain how new and groundbreaking genetic testing can help you research your ancestry
According to American Demographics, 113 million Americans have begun to trace their roots, making genealogy the second most popular hobby in the country (after gardening). Enthusiasts clamor for new information from dozens of subscription-based websites, email newsletters, and magazines devoted to the subject. For these eager roots-seekers looking to take their searches to the next level, DNA testing is the answer.
After a brief introduction to genealogy and genetics fundamentals, the authors explain the types of available testing, what kind of information the tests can provide, how to interpret the results, and how the tests work (it doesn't involve digging up your dead relatives). It's in expensive, easy to do, and the results are accurate: It's as simple as swabbing the inside of your cheek and popping a sample in the mail.
Family lore has it that a branch of our family emigrated to Argentina and now I've found some people there with our name. Can testing tell us whether we're from the same family?
My mother was adopted and doesn't know her ethnicity. Are there any tests available to help her learn about her heritage? I just discovered someone else with my highly unusual surname. How can we find out if we have a common ancestor? These are just a few of the types of genealogical scenarios readers can pursue. The authors reveal exactly what is possible-and what is not possible-with genetic testing. They include case studies of both famous historial mysteries and examples of ordinary folks whose exploration of genetic genealogy has enabled them to trace their roots.
PUBLISHERS WEEKLY
Genetic typing is the newest tool for amateur genealogists, and it's enthusiastically espoused by the experienced authors of this useful guidebook (Smolenyak is the lead researcher for PBS's Ancestors and the author of In Search of Our Past Ancestors; Turner contributes to the GENEALOGY-DNA mailing list). How does it work? By tracing one's "DNA heirlooms," the two forms of DNA that are passed on in a family from generation to generation. These "heirlooms" include genetic markers on the Y chromosome, passed on by fathers, and mitochondrial DNA, passed on by mothers. If it sounds hard to understand and do, the authors reassuringly offer clear explanations of the science and how to use it. DNA typing can tell you if you're related to someone with the same surname, pinpoint a certain ancestor and verify your other research. But, as the authors warn, it could also prove your previous assumptions wrong or uncover unwanted information, such as that a family member was adopted. If you have been researching your family's history and have unanswered questions, this enlightening book may offer some answers; at the very least, it will walk you through the benefits and drawbacks of DNA testing.
