Genetic studies in Poland

Blood specimens were studied from 213 persons aged 3-51 years, in Olkusz, a town between Krakow and Katowice in south Poland. The data show general similarity in blood groups and red cell enzymes to those from other central European populations, but in several systems there are suggestions that Polish frequencies are somewhat peripheral, for example phosphoglucomutase, acid phosphatase, esterase D, while in others where clines exist the results fit well into those expected from the geographical position of the sample.
