Updated population genetic data of 15 autosomal STR loci in a Shandong Han population from East China and genetic relationships among 26 Chinese populations.

Our study updates the Shandong Han population database with a large sample size. These 15 STR loci in the Shandong Han population are more polymorphic and discriminatory than shown in previous data, which could be more applicable to personal identification and paternity testing, as well other population genetics studies.
