title: Continuity of Y chromosome haplotypes in the population of Southern Poland before and after the Second World War.
abstract: The Polish population is reported to be very homogenous as far as Y chromosome polymorphism is concerned. One of the hypotheses that explains this phenomenon is based on the assumption that massive migrations that took place in Poland after the Second World War might have evoked such an effect. Thus, knowledge of the pre-war frequencies of Y chromosome haplotypes in different parts of the country would be a useful tool in testing such a hypothesis. We have collected 226 DNA samples, together with family history data, from males living in the rural area of Małopolska, Polish Southern border region. Based on donors' family histories we were able to reconstruct an 'ancestral' subpopulation of 108 males whose ancestors had inhabited the area before both World Wars. We have analyzed 12 Y-STR loci: DYS19, DYS385, DYS389I&II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438 and DYS439 in all the collected samples. Comparisons of our contemporary and 'ancestral' population samples with other Polish and Central European populations showed that the population of Southern Małopolska is very closely related to other Polish and Slavic populations. The above-mentioned observations suggest that the population of Southern Poland could have been highly homogenous even before the Second World War.
