Release 68 - 2022/Oct/29

To allow validation or testing, we have moved the former database version R67 to a special archive available at

Release 67 - 2022/Feb/07

Implementational change to YHRD search: We have changed the way searches are performed. We are glad to introduce a new search option at YHRD: a selectable “Kit”. Please read about the new search here.

Convenient collection of Population Studies: At each National Database or Metapopulation summary, all population studies being used to assemble the collection are listed for your convenience.

Removal of YHRD uncommonly used search features: In order to further reduce the complexity of YHRD (and thus make it easier to maintain), we have decided to remove some uncommonly used features of the YHRD search: ancestry information (minimal), ancestry information (Yfiler) and ancestry information (1-step neighbors).

Moved from Google Maps to OpenStreetMap: As Google Maps does not comply with our understanding of privacy protection, we have moved from Google Maps to leaflet.js using OpenStreetMap map data. Please make yourself familiar with those new maps e.g. at Western-European Metapopulation or Y-SNP M231 defining Haplogroup N.

AMOVA removed: Due to the decreasing use and the increasing maintenance work, we decided to remove the tool AMOVA from the public area of YHRD. If you need to use AMOVA, please contact us or use other software for population genetic data analysis (e.g. ARLEQUIN).

Contributions: We have added information on the publication (if already availabe), a statement on legacy data and the nature of data submitted via personal communication (if applicable) to the contributions page. As an implementational side effect, we had to renumber some of the accession numbers without affecting consistency of the data.

Release history: Added detailed information on the effect of YHRD updates to Metapopulations and National Databases.
