Yfull is not a provider of Y-DNA or NGS tests, but an analysis service for NGS with a database in which data from NGS tests are compared and analyzed, regardless of the provider. This allows to compare the results of currently 13 sources. (Commercial companies and scientific studies). The results are presented in the form of a Y-tree in different representations. The kits are presented anonymously and the Y-tree (as well as the mt-tree) is publicly accessible for everyone. This makes it not only an enrichment for the submitters, but also for everyone who is concerned with the topic Y-tree (as well as mt-tree).
