I did a comparison of this sort and you can read about it in a paper on my site that was published in JOGG. AT this link, it's the first paper. The reason you're not getting answers from people is because this is very complex and as Sam said, it's an imperfect science. http://www.dnaexplain.com/Publications/Publications.asp Roberta EStes -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Sam Eaton Sent: Saturday, March 31, 2012 4:12 AM To: [email protected] Subject: [AUTOSOMAL-DNA] Comparisons of ethnicity between FTDNA and 23andMe Gail, We are at the cutting edge of science. Definitive answers don't exist. I expect that answers will become more consistent as time goes by, sample size increases, more people are tested and the history of more SNPs are better understood. If you like third opinions, http://www.dnatribes.com/ specializes in this sort of analysis. Note, while I have had them examine my 23andMe Raw Data, I have no idea how their accuracy compares to either FTDNA or 23andMe. www.GEDmatch.com provides a home for people trying to experiment with and research these sorts of issues. Most people like predictability and order. A few like Scientists and Soldiers understand that the world is chaotic and our knowledge of the world is imperfect. Sam ----------------------------------- Thanks to a number of persons on other "lists", (namely Diana, Leon, Greg), I now direct my query to this list. Although I sent this same request for aid to the Yahoo 'Newbies' list (no response) and the genealogy DNA list (no response), I am trying again, but on this list... I have administration of 3 paternal cousins and 2 siblings and have tested them with 23andMe and FTDNA for atDNA. I am needing help with understanding the diverse results reported by FTDNA "Population Finder" (within 'Family Finder') and 23andMe "Ancestry Painting". If help not available from this list, could I please be advised as to whom to ask, (or from which list to seek an answer) please? I provide a matrix of the results of all 6 of us at http://bit.ly/Gail_atdna and request help in understanding the reported differences, please. By the way, I understand that the transferred results are highly likely to read slightly differently to the pure FTDNA results and I also understand that the % may well be a little different (including margin of error) due to differing autosomal recombinations. But I do not understand me (Gail) having a concise African heritage as opposed to my 2 siblings "D" and "N" having a more general and extended middle East heritage. Nor do I understand tester #6 "J" having such a strong difference to the remainder of his 5 * 1st cousins - they/we/I are/am all his maternal 1st cousins. And by the way, yes, we are definitely all genetically 1st cousins or siblings - I checked :-) Kind regards Gail Riddell ______________________________ For answers to Frequently Asked Questions about mailing lists, please see: http://dgmweb.net/MailingListFAQs.html ------------------------------- To unsubscribe from the list, please send an email to [email protected] with the word 'unsubscribe' without the quotes in the subject and the body of the message

Roberta Your paper covers my questions (and more). (You are to be congratulated for preparing such an in-depth analysis).
