Bettinger, Blaine T. and Wayne, Debbie Parker (November 18, 2016). Genetic Genealogy in Practice. Published by National Genealogical Society, Inc. ISBN 9781935815228.
From the publisher's book description: "At their own pace, readers learn the basic concepts of genetic genealogy. They then build on that knowledge as they study the testing, analysis, and application of YDNA, 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."
This excellent workbook by two industry experts covers genetic genealogy theory and current tests and tools. About one third of the book comprises exercises (with solutions) exploring how to apply the theory in practice to a wide range of genealogical problems. The book also covers how to present results professionally.
I would recommend it to genealogists with an academic mindset but anyone with an interest in the subject can learn from it.
