ABSTRACT Human Y-chromosomal short tandem repeat (miniY-STR) with short amplicon lengths is useful in forensic applications, especially in the analysis of degraded DNA samples. The present study aims to investigate the population database of six miniY-STR (DYS570, DYS556, DYS576, DYS522, DYS508, DYS540). 307 blood samples were taken from the Han population, and 253 samples were taken from the Zhuang population. The amplification product lengths detected ranged from 95 to 170 bp. A total of 395 haplotypes, 303 of them unique, were found. The haplotype diversity of the Han was 0.9980 and of the Zhuang 0.9965, indicating a high discriminating power of these six miniY-STR loci in these two populations.
