Comparison of Y-STR polymorphisms in three different Slovak population groups.

Eleven Y-chromosomal microsatellite loci included in the Powerplex Y multiplex kit were analyzed in different Slovak population samples: Habans (n = 39), Romanies (n = 100) and Slovak Caucasian (n = 148) individuals, respectively, from different regions of Slovakia. The analysis of molecular variance between populations indicated that 89.27% of the haplotypic variations were found within populations and only 10.72% between populations (Fst = 0.1027; p = 0.0000). The haplotype diversities were ranging from 0.9258 to 0.9978, and indicated a high potential for differentiating between male individuals. The study reports differences in allele frequencies between the Romanies, Habans and Slovak Caucasian men. Selected loci showed that both the Romany and Haban population belonged to endogamous and relatively small founder population groups, which developed in relatively reproductive isolated groups surrounded by the Slovak Caucasian population.
