At tellmeGen, we are constantly working to improve the quality of our service, including adding new populations to our ancestry analysis. In June 2025, we released an update to our ancestry test, moving from version 3 (V3) to version 4 (V4). This update was implemented automatically and free of charge for all users, without them having to take any action.
The main difference between V3 and V4 is the increase in the number of ethnic populations, from 53 to 93. This expansion, together with the increased number of reference individuals in each population, has allowed us to refine the algorithm and improve the reliability of the results. As a result, users' ethnicity estimates are now more specific and accurate.
Although some users may notice changes in their results with this new version, this is completely normal and does not mean that their previous results were incorrect. These changes reflect scientific advances in ancestry and population origins research, making the new results more accurate.
It is important to note that, at tellmeGen, we regularly update all users' results to the latest version free of charge and notify them of the update. If a user prefers their V3 results and does not wish to switch to V4, they can choose to keep their previous results without any problem.
