Based on the descision of the Lineage Marker Committee of SWGDAM the complete US YSTR database (release 4.2.1) is transferred from usystr.org and included in the YHRD. US colleagues can analyze Y-STR profiles according to the current SWGDAM guidelines of 2014 including theta correction und one-sided confidence interval. Please note that the new guidelines in Germany (2018) recommend the DL values to calculate match probabilities. These values are recalculated from release to release for all 33 metapopulations. Overall the YHRD database increases again drastically with now >250k haplotypes (1221 population samples from 135 countries).
