   What does YHRD stand for?

   • Provision of advanced tools and further resources concerning Y-STRs and Y-SNPs. Y-STR Haplotype Reference Database (YHRD) is a searchable worldwide database of Y-STR Haplotypes in various formats along with tools build upon their distribution.

   What is a YHRD database?

   • The YHRD is a database, which consists of 5 separate datasets with different resolutions (see Table 1). Datasets are collections of haplotypes all defined for a certain set of Y-STR markers (see Table 1, Table 2) and might therefore be part of other, bigger datasets.

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

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

   How is YHRD structured?

   • YHRD is structured by the assignment of each submitted population sample to a set of populations sharing a common linguistic, demographic, genetic or geographic background (metapopulations). This principle facilitates the statistical evaluation of haplotype matches due to a significant enlargement of sample sizes.

   How is YHRD developed?

   • YHRD has been developed following the behavior driven development (BDD) principle for the frontend and using the test driven development (TDD) principle for the database backend.
