Abstract:
Genetic markers, such as single nucleotide polymorphism （SNP）, insertion/deletion （InDel）, were discovered and widely used with the development of whole genome sequencing and bioinformatics technology. The origin and genetic structure of the modern population had been gradually revealed from the perspective of genetics. The study on biogeographic ancestry inference in the field of forensic genetics emerged and developed rapidly, providing clues and scientific basis for the determination of investigation direction and for the narrow of the scope of investigation in the process of case investigation. This paper briefly reviews the research progress, inference methods and development trends of DNA ancestry inference technology.
