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."
I would recommend it to genealogists with an academic mindset but anyone with an interest in the subject can learn from it.
