Abstract:
This paper describes the polymorphism of a new locus DYS439 in a Polish population sample of 198 males. To correctly type DYS439 alleles, a sequenced allelic ladder was constructed. In an analyzed population sample 6 of 7 alleles identified to date were found (17, 19-23). The most frequent allele was 19 with a frequency of 0.4343. Calculated gene diversity value for DYS439 locus is 0.70 and is one of the highest for Y-STR loci analyzed in our population to date. Moreover a comparison of homogeneity distribution of DYS 439 alleles between different populations was analyzed. Very significant statistical differences (p < 0.0000) were observed between our population and four European population samples (Italy, Portugal and Spain).

Comparing Copy Number Variations and SNPs
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...
