Abstract
AGCU 21+1 STR kit contains 21 non-combined DNA index system (non-CODIS) short tandem repeats (STR) loci and a sex-determining locus amelogenin. In this study, we evaluated the genetic diversity and forensically relevant population statistics of 21 non-CODIS loci in 210 Chinese Han individuals from Chengdu city, Sichuan province, Southwest China. No significant deviations from Hardy-Weinberg equilibrium were observed within the 21 non-CODIS STR loci. The combined power of discrimination (CPD) and combined power of exclusion (CPE) were 0.99999999999999999994278, 0.999999355 respectively. To reveal interpopulation differentiations of mainland population of China, a neighbor-joining (N-J) phylogenetic tree was constructed based on Nei's genetic distances among Chengdu Han and 25 published populations. The phylogenetic analyses indicated that Chengdu Han population keeps a close genetic relationship with other Han populations.
