JGG | Center for Archaeological Science, Sichuan University - Yuan Huijun, He Guanglin, Wang Mengge, et al. Review of the Latest Advances in Genetic Genealogy in the Reconstruction of Ancient Human Social Structures and Criminal Intelligence打击 Research

In recent years, with the development of DNA sequencing technology, the advancement of computational methods, and the establishment of genome databases (Figure 1), forensic investigative genetic genealogy (FIGG) analysis has gradually matured. FIGG combines modern molecular biology techniques with traditional genealogy methods, providing important clues for identifying unknown individuals in major and difficult cases (Figure 2). The DNA Doe Project (DDP) used FIGG to identify the victim of the "Buckskin Girl" murder case, and the infamous "Golden State Killer" case was also solved through FIGG. By analyzing shared alleles and haplotypes, genealogical techniques...

Center for Archaeological Science, Sichuan University published in top forensic science journal FSIG, reporting that global population non-CODIS STR profiles provide new ideas for forensic complex DNA analysis

Short tandem repeats (STRs) account for approximately 6% of the genome and are a class of highly polymorphic genetic markers. Since their first application in forensic DNA analysis in the 1990s, STRs have played an important role in population genetics research, personal identification, biogeographic ancestry inference, parentage testing, and kinship analysis. Currently, mainstream STR detection kits generally contain only 20-30 STR markers, including the core loci of the FBI Combined DNA Index System (CODIS), which are difficult to meet the increasingly complex needs of forensic DNA analysis. High-throughput next-generation sequencing technology...
