Just in case anybody else has wondered about uploading data from FTDNA to 23andme, the answer is a no no. See below for the answer to my query - I just wish I understood it all!!. Bryan Caroline, Jun 17 07:19 am (PDT): Hello Bryan, Thank you for contacting the 23andMe Team. At this time it is not possible to upload genetic data from other ancestry services into a 23andMe account for the purpose of comparison. The technology that we use, the Illumina OmniExpress Plus, analyzes approximately 1,000,000 SNPs that cover the entire genome. Although this is still only a fraction of the more than 10 million SNPs that are estimated to be in the human genome, these 1,000,000 are specially selected because they provide a lot of information about other nearby SNPs. In addition, we have hand-picked more than 30,000 additional SNPs of particular interest from the scientific literature and added them to the chip. As a result, we can provide you with unique, genetic information available through no other service. 23andMe probes the mitochondrial DNA at more than 2000 positions that are known to vary from one person to the next. This level of resolution is less detailed than full sequencing of all 16,569 base pairs in the mitochondrial genome. 23andMe's paternal ancestry tool analyzes SNPs, or single nucleotide polymorphisms on the Y chromosome, to extract information from DNA. Most genetic ancestry services, in contrast, analyze a different component of the Y chromosome, known as the STRs, for short tandem repeats, to reach their conclusions. The information provided by STRs and SNPs is not directly comparable. Please let us know if we can be of further assistance. Best Regards, The 23andMe Team
