A Beginner's Guide to DNA Testing and Genetic Genealogy

Have you ever thought of or sought for the answers to the following questions? 

  • "Which is the best testing company for adoptees?"

  • "Why did I receive completely different ethnicity results when I uploaded my AncestryDNA results to GEDmatch and MyHeritage?"

  • "My brother and I sent our samples into AncestryDNA recently. We have the same biological parents, but our results were significantly different. Isn’t genetic testing no better than astrology?"

  • "On 23andMe in DNA relatives, a woman is my father's half-sister. He doesn't have a half-sister. What is going on?"

The genealogy bargain hunter, Thomas MacEntee praised Andy's book by saying: 


"If you have an interest in DNA testing, you’ll love this book . . . even if you’ve been working DNA result for some time now. Andy and Devon cover every possible question from the basics including DNA test accuracy, to the scientific covering SNPs, centimorgans, and segments. And there is also the occasional “bizarre” question such as whether 23andMe is owned by Google and more."
