Important Change to Big Y Analysis
I've resisted writing about the change that has been taking place at FamilytreeDNA with the upgrade and to how they will analyze Big Y results going forward. The reason for the delay was to allow the dust to settle and see how the process was progressing in order to give you the most accurate update to what is going on. This affected our DNA group in that we have four members of our group who are anxiously waiting for their results. The untimely setback for our Sproul testers during this upgrade is still a positive move for our group. For one, these four members are the first Big Y testers for our project so we have no members waiting to have their previous results to go through the re-read. What is occurring is how the analysis program reads the DNA results. Each SNP that is targeted for genealogical analysis is assigned a numeric location in our strand of DNA. What the change is doing is adjusting the numeric location for that SNP giving it a more refined result. It will also
