Objective:
To investigate the polymorphisms of 15 STR loci of Han population in Yan'an.
Methods:
Blood samples were obtained from 100 unrelated Han individuals in Yan'an. DNA templates were screened by AmpF/STR Identifiler kit and ABI3100Avant DNA analyzer.
Results:
The allele frequencies of 15 STR loci ranged from 0.005 to 0.550, and the genotype frequencies ranged from 0.010 to 0.310. The combined match probability was 2.5x10(-17) and combined EPP was 0.999999999.
Conclusions:
The 15 STR loci used in this study were highly polymorphic in Han population in Yan'an and suitable for population study and forensic cases in this region.

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%...
