Abstract

A large database on the Qatari population was created for comparison with other databases from
the Arabian Peninsula and the Middle East. We provide a study of 23 Y-STR loci included in
PowerPlex Y23 (Promega, USA) that were genotyped to produce haplotypes in 379 unrelated
males from Qatar, a country at the crossroads of migration patterns. The graph of the population
Q-matrix was created using Y-STR data from 134 Middle Eastern and African populations (11,305
individuals), and it revealed a stronger sub-grouping of populations within each ethnic group.
The estimated migration rate between the Qatari and other Arabian populations was inferred
using Bayesian coalescence theory in the Migrate-n program. According to the Gene Flow study,
the main migration route was from Yemen to Kuwait through Qatar. Our research, using the
PowerPlex Y23 database, shows the importance of gene diversity, as well as regional and social
structuring, in determining the utility of demographic and forensic databases.
