Due to the virtues of no stutter peaks,low rates of mutation,and short amplicon sizes,insertion/deletion(InDei)polymorphism is an indispensable tool for analyzing degraded DNA samples from crime scenes for human identifications(Wang et al.,2021).Herein,a self-developed panel of 43 InDei loci constructed previously by our group was utilized to evaluate the genetic diversities and explore the genetic background of the Han Chinese from Beijing(HCB)including 301 random healthy individuals.
