Why do my results change with different versions of ancestry? 

At tellmeGen we are working to develop and improve new mechanisms to estimate the ancestry of our users. Therefore, there are differences between the different versions of our methodology, either by the addition of new genetic populations to the ancestry DNA test, or by a change in the calculation algorithm, ensuring in the most recent version a higher quality and accuracy. In addition, it should be noted that we periodically update the results to the most recent version free of charge to all our users, notifying them of the update.
