[Regional differentiation of blood group frequencies in the Polish population]

The paper presents frequency distributions of alleles of eight blood group systems (ABO, MN, Rh, Hp, Gm(a), AcP, PGM1, EsD) in the Polish population. The blood group determinations concerning 10521 individuals (were carried out during paternity testing in regional serological laboratories throughout the country). Detailed information on the place of residence for all the subjects was also available. Blood group frequencies of subjects living in five regions of Poland were compared with historical date. The analysis has shown an almost complete disappearance of genetic variability in respect of the analysed traits between local populations inhabiting various regions of Poland.
