Those reports you are referring to are applications that were designed by various individuals. They are based on test groups from various world populations. Each application should have a link to the various developers. Those links will further explain the application, what test group results were used, etc. The most recent of these applications are World9 and HarappaWorld. The others have been around for several years. The applications are designed to give you a more definitive look at your genetic makeup than the applications used by FTDNA and 23andMe and which world populations you mostly closely match. You'll notice the results may vary from application to application. Be sure to click on the Oracle button where available.
