Hello all- I'm giving an intro workshop for our genealogical society on "Making the Most of your DNA Test Results" tomorrow for Family History Month. I'm profiling all 3 major genetic genealogy tests, and their strengths and weaknesses, and how best to make use of their tools (it's only 2 hours so it will be high level) Anyone have any current info on database size for AncestryDNA, 23andMe, FamilyTreeDNA? I have info from June but wonder if there's anything more current. Of course, I'll suggest "fishing in all 3 ponds" but for people who are just getting started, that will probably seem like a bit much. Also, I started thinking about lab sample practices...I know FT DNA keeps samples, but not sure about the other 2. I think don't think it'll come up, but it's a good thing to know, especially if you have an older person who has only tested with AncestryDNA. Seems like the follow-on testing would be kind of limited. Thanks in advance, Mary E Hall

Mary, The chart at this link should be helpful. http://www.isogg.org/wiki/Autosomal_DNA_testing_comparison_chart Regards, Larry ________________________________ From: Mary E Hall <just23gen@gmail.com> To: autosomal-dna@rootsweb.com Sent: Sunday, October 13, 2013 2:00 PM Subject: [AUTOSOMAL-DNA] DNA test lab profile Hello all- I'm giving an intro workshop for our genealogical society on "Making the Most of your DNA Test Results" tomorrow for Family History Month.  I'm profiling all 3 major genetic genealogy tests, and their strengths and weaknesses, and how best to make use of their tools (it's only 2 hours so it will be high level) Anyone have any current info on database size for AncestryDNA, 23andMe, FamilyTreeDNA?  I have info from June but wonder if there's anything more current.  Of course, I'll suggest "fishing in all 3 ponds" but for people who are just getting started, that will probably seem like a bit much.
