    3. Dear All, I thought I would let you know that over the past week or so I have been running comparisons between the 23andMe v5 data and the data from the other companies to see how many autosomal SNPs overlap between the datasets. See the top chart at https://isogg.org/wiki/Autosomal_SNP_comparison_chart#Autosomal_SNPs. I have several more Genes for Good comparisons to run and then this chart will be complete. My initial impression is that 23andMe is doing a reasonably good job with imputation for the matching segment data for DNA Relatives. My impression is that the imputation for the Genesis Project at GEDmatch is not quite as good so far. It is unfortunate that this "schism" exists for 23andMe v5 and Living DNA data, but that is the way that it is. I wonder if and/or when Family Tree DNA will be converting over to the Illumina Global SNP Array chip. My suggestion at this point is that it would be prudent to test all of your closest family members on a GSA chip (23andMe v5 or Living DNA) so that you can upload the data to GEDmatch and be assured you will being seeing all of your matches who have tested only on a GSA chip who share reasonably long (say 15cMs to 30 cMs) DNA segments with your family or you. Mike, in my opinion all serious autosomal genetic genealogists test at 23andMe. 23andMe has well over 2 million people in their database so it is would be unwise for a serious autosomal genetic genealogist to not test there. 23andMe certainly has the best DNA comparison tools relative to Ancestry.com, MyHeritage and FTDNA's Family Finder. GEDmatch offers unsurpassed genetic comparison features that we need as well.

    3. I'm confused, nothing new there. Tim, are you recommending that "all serious autosomal genetic genealogists test at 23andMe"? So then, if you upload your 23and Me results to FTDNA, where you have already tested, or to Gedmatch, which already has your Family Finder results, are there any conflicts? One person, 2 sets of results?

    3. Bill, This happens sometimes and it is not an issue. I've tested, with an original saliva sample at FTDNA, 23andMe, AncestryDNA, MyHeratige, LivingDNA, and Genos. I got an account at each company. I uploaded the first 4 to GEDmatch and got a different Kit ID each time - it looks like 4 different people with the same email. Others have done this too. Some get confused or frustrated and upload the same kit again - I've seen up to 4 kits from the same AncestryDNA download (each got a different kit ID). It's OK to do this, but anyone who does, should make all but one kit "Private". You are not permitted to upload an atDNA kit at FTDNA if you already have an atDNA kit there - only one atDNA kit per customer. So there are no conflicts. Sometimes it is confusing when you get kits from GEDmatch from the same email as a Match more than once - is it the same person, or parent child, or what (sometimes they use the same name, sometimes its altered slightly, sometimes a lot). Since I Triangulate my Matches, I'm comparing them to each other. If they share about 3600cM that's usually a parent/child. I then rerun the comparison with the graphics on - a parent/child will have some differences, a duplicate kit will be solid blue. Hope this helps.
