Allele frequency data for ten STR loci: D3S1358, vWA, D16S539, D2S1338, D8S1179, D21S11, D18S51, D19S433, TH01, FGA were estimated in a sample of 350 unrelated individuals in Central Poland population (Lodz region). The accordance with the Hardy and Weinberg equilibrium (HWE) for all investigated loci was proved. The allele distributions were compared to the similar data for other populations.
