     YHRD : Y-Chromosome STR Haplotype Reference Database

2. People also ask

   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 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 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.

   What information does YHRD provide?

   • YHRD provides information on each metapopulation including the assigned populations, a map, its common haplotypes (Figure 23b) and applicable calculation methods. Each national database in the YHRD comprises all individuals sampled in a particular country regardless of the ancestry of the individuals (Figure 24).

   How many YHRD datasets are there?

   • Table 1. Compositions of the five YHRD datasets as of release 48 (November 2014). Each row represents a separate dataset with a name and the defining markers followed by the count of haplotypes and the number of populations, national databases and metapopulations structuring the dataset.

   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.
