Genetic Genealogy in Practice

book cover Genetic Genealogy in Practice provides family historians and genealogists who have begun to explore genetic genealogy easy to understand and practical information that they can apply to their research. The authors tackle this complex topic one step at a time. Readers learn the basic concepts of genetic genealogy. They then build on that knowledge as they study the testing, analysis, and application of Y-DNA, X-DNA, mitochondrial DNA (mtDNA), and autosomal DNA (atDNA) to reach and support genealogical conclusions. Each chapter includes exercises with answer keys for hands-on practice.

Genetic Genealogy in Practice is available for purchase in the NGS online store in print or as a Kindle e-book at Amazon.
