In practice, the detection of complex biological samples and the identification of complex kinships are challenging current biological technologies. Novel DNA technologies are also introduced into forensic genetics to improve the power of analysis. Next-generation sequencing (NGS) has several advantages, such as high-throughput and low cost, and can obtain detailed DNA sequences and relative contents of targeted regions, which will improve the detection of biological samples to help the analysis of forensic cases. The application of NGS in forensic genetics has received extensive attention and reports on the application of NGS in forensic genetics are increasing. In this study, we summarized the progress in the application research of NGS in the forensic genetics including the detection of genetic markers and their analytical methods. This will provide guides for related studies and forensic applications.
