ARCHIVED: DNA with Blaine Bettinger (discussion)

Thanks to our friend Blaine Bettinger for the informative discussion about DNA test results and the impact this can have in our genealogical paper-trail. We managed to discuss autosomal, yDNA and mtDNA testing; mirrored trees, triangulation, and a bit about ethical issues when sharing DNA results.
  • Endogamy includes hundreds of  years of intermarriage so it's all about the length of DNA segments.
  • "Fish in multiple ponds" means test and/or upload your DNA to as many DNA sites as possible, to increase the likelihood of finding a match with someone who has tested with that other company.
  • Recombination means that although my brother and I inherit 25% of our DNA from our grandparents, we may inherit different segments.
Blaine's blog is The Genetic Genealogist

There you can find out more about the upcoming book Genetic Genealogy in Practice he co-authored with Debbie Parker Wayne. It is "directed to genealogists of all levels, from beginner to intermediate to advanced. For the very first time, GGP offers hands-on exercises in areas of Y-DNA, mtDNA, X-DNA, atDNA, the Genealogical Proof Standard, ethics, and more." It's a workbook with 75 exercises.

Blaine recommends the wiki at ISOGG (International Society of Genetic Genealogists) located here:

In addition to spreadsheets, Blaine uses Genome Mate Pro to manage DNA comparisons. Find out more here: 

For information about X-DNA Charts, Blaine has several great suggestions here:
