Abstract
A 21-plex DIP (deletion and insertion polymorphism) panel has a good performance in analyzing biogeographic ancestry in three main global population groups (European, African, and Asian). This panel was used to investigate 450 unrelated individuals in seven Chinese ethnic groups (Han, Dong, Miao, Zhuang, Uyghur, Tibetan, and Mongolian). Allele frequencies were calculated. Mho (mean value of observed heterozygosity) ranged from 0.3019 to 0.4367, MHe (mean value of expected heterozygosity) ranged from 0.31175 to 0.38341, CMP (combined matching probability) ranged from 3.5834E-07 to 2.5985E-06, CDP (combined power of discrimination) ranged from 0.99999740150 to 0.99999964166, and CPE (combined power of paternity exclusion) ranged from 0.85884504 to 0.97949131. The results suggested the potential of the panel for individual identification and paternity testing in Chinese populations. Pairwise genetic differences Fst values (-0.00091 to 0.05873) and the analysis by STRUCTURE indicated that Chinese populations have good internal consistency.
