[Polymorphism of the YCAII locus in a Polish population].

This paper describes the polymorphism of a YCAII locus in a Polish population sample of 189 males. In an analyzed population sample 6 of 11 alleles identified to date were found (www.ystr.org). The most frequent allele was 19 with a frequency of 0.4343. The calculated gene diversity value for YCAII locus is 0.62 and possesses a rather moderate discrimination power for loci analyzed in our population to date. Comparison of homogeneity distribution of YCAII alleles between different populations was analyzed. Very significant statistical differences (p<0.0000) were observed between our population and Italian, German, Lithuanian, Latvian and Estonian populations. No statistical differences were observed between the Polish and Slovenian population sample (p=0.40).
