Folks with Full Y DNA results coming in may also want to consider the following option from Mark Jost: MJost on Full Y DNA analysis Posted at R1b-L21 Project at yahoo.com So, we, the Full Y DNA Testers have or are about to received our long awaited results, and will soon discover that the journey is not finished yet. More work will be needed. To further this process the individual HaplogroupCompare" and other reports will be required for cross-reference and other tasks. These reports will identify your novel SNP(s) along with a number of "private" SNPs. Novel SNP(s) that are derived, and also found in other datasets, either other FGC- L21er's and/or are found in other major Y-DNA datasets. We all want our newly discovered SNP(s) placed on the Y-DNA Tree for all to see. ISOGG now has the 'Final' word on the placement aspect. The first step in this process is that ISOGG requests one derived sample to be sequenced (=confirmed) with Sanger. This is one of several criteria required for Tree placement. This is required to make sure that it's not an artifact of the analysis method used. When this is confirmed, there will be the need for more confirmations (other methods are considered such as NGS results) from other kits within- and outside your Haplogroup group to satisfy the other criteria. To assist in confirming validity for any new novel SNPs found in your FGC reports by further conducting the Sanger testing, I am working with a well known yet un-named "Expert" with this process who can produce the primers and run the initial SNP testing required by ISOGG. This is a US based company. I would like to coordinate the above process for my self and other FGC Full Y testers. MJost In answer to my query for the M222+ folks with Full Y results: I am looking for the completed FGC result files that are sent to each individual, for now. The file names contained are: VariantCompare haplogroupCompare gtype These files are contained along with others in a Zipped format. They can be forwarded directly to me for review. I will then forward to the yet un-name company for their experts to verify and create a primer and submit payment to validate the new novel SNP found as the first step in the process of getting it on the ISOGG tree. From these files I will be able to evaluate which other FGC returned kits contain either an ancestral or derived states. Additional testing of others maybe required. Example would be if you are currently DF13* and it reports that four DF13 subclades indeed have the referenced ancestral allele, then only the remaining ISOGG subclades will need to be tested. Remember these steps are needed to prove that the new novel SNP is valid and further correctly placed on the Tree. MJost
