We have analyzed the distribution of allele frequencies at two short tandem repeats loci (D2S1338 and D19S433) in a multinational sample of Bosnia and Herzegovina (B&H) residents. A total of 110 unrelated male and female individuals (Caucasians) from different regions of B&H were sampled for the analysis. We ensured that the sample reflected approximate proportional participation of the three main ethnic groups in the population of B&H (Bosniacs-Muslim [45%], Serbs [34%], Croats [21%]).
