Population genetic data for 11 STRs included in the Humantype Chimera kit were obtained by multiplex PCR and subsequent automated fluorescent detection (ABI 310) from a sample of 200 unrelated individuals of both genders belonging to the Belarussian minority residing in the region of Podlasie (Northeastern Poland). The objective of the investigations was determination of 11 STRs frequency and calculation of parameters of their usefulness in medicolegal examinations. The genotype distributions conformed to HWE for all the analyzed loci. The highly polymorphic systems exhibit a high degree of informativeness and are a potential extension to CODIS loci, particularly in kinship analysis and deficiency cases.
