Genetic characterisation for Yan'an Han population in Northern Shaanxi Province, China, via 38Y-STRs using Yfiler™ Platinum.

Background: Haplotype/allele frequency data of Y-chromosomal STR loci in ethnically diverse populations are essential for forensics, anthropology and genealogy. However, genetic structure and forensic characterisation of the Chinese Han population residing in Yan'an, in the Northern Shaanxi Province, remain unclear.

Aim: To assess forensic efficiency for 38 Y-Chromosomal STR loci in Yan'an Han population and reveal the population genetic relationships between Yan'an Han and other populations at a nationwide and worldwide level.
