The mutation rates at DYS576 and DYS627 were higher than 1 × 10 −2 in Northern Han Chinese, whilst the mutation rates at DYF387S1a/b, DYF404S1a/b, DYS449, DYS518, and DYS570 were lower than initially defined. ![]() In 308 father–son pairs, 268 pairs occurred mutations at a single locus, 33 pairs at two loci, six pairs at three loci, and one pair at four loci. Sanger sequencing or MPS was employed to confirm 356 mutations from 104 468 allele transfers generated from CE, where 96.63% resulted in one-step mutations, 2.25% in two-step, and 1.12% in multi-step, and the overall ratio of repeat gains versus losses was balanced (173 gains vs. Hereof, we found 16 novel RR variant alleles and firstly identified two SNPs (rs2016239814 at DYS19 and rs2089968964 at DYS448) and one 4-bp deletion (rs2053269960 at DYS439) that had been validated by the Database of Short Genetic Variation. ![]() When comparing alleles at 24 overlapped Y-STRs between the ForenSeq™ deoxyribonucleic acid (DNA) Signature Prep Kit on the MiSeq FGx® Forensic Genomics System and the Goldeneye® DNA ID Y Plus Kit on the Applied Biosystems™ 3730 DNA Analyzer from 308 father samples in mutational pairs, 258 alleles were detected by massively parallel sequencing (MPS) typing including 156 length-based alleles that could be obtained by capillary electrophoresis (CE) typing, 95 repeat region (RR) variant alleles and seven flanking region variant alleles. The average gene diversity (GD) value was 0.6934 with a range from 0.1051 at DYS645 to 0.9657 at DYS385a/b. In 2 548 father samples, 2 387 unique haplotypes were detected with the haplotype diversity and discrimination capacity values of 0.999 956 608 and 0.96 741 007.
