   What does YHRD stand for?

   • The “Discrete Laplace method” which is implemented in the Y Chromosome Haplotype Reference Database (YHRD) is a model-based extrapolation method which makes use of an in-depth analysis of Y-STR profiles in more than thousand worldwide population samples.

   What is the Y-chromosome haplotype reference database (YHRD)?

   • The Y-Chromosome Haplotype Reference Database (YHRD) now includes 135 national databases which have been populated over the past 20 years. The YHRD project was started in 1999 with a collection of 3,825 haplotypes typed in 48 populations for up to 13 Y-STRs.

   Why is YHRD important?

   • It can be used to estimate haplotype frequencies with a better approximation than the counting method. Moreover, the YHRD is a useful resource to infer the ancestry of an unknown male person due to the availability of a consensus phylogenetic tree and geographic and ethno-linguistic information assigned to each profile.

   What happened to the Y-STR database?

   • As of November 26, 2018, 217,758 search queries of the database had been performed. The U.S. Y-STR Database haplotypes have been permanently transferred to the Y- Chromosome Haplotype Reference Database and the U.S. Y-STR Database will be decommissioned. Decommission dates is scheduled for June 30, 2019.

   How does YHRD validate incoming data?

   • All incoming data are validated first by the submitter using YHRD online tools and then by the curators before being uploaded and accepted for publication. To calculate the Y-STR profile frequency constant and variable estimators can be used.
