摘要：The short tandem repeats (STRs) is a kind of unstable short nucleotide repetitive sequence which can be inherited. STRs distribute extensively in human genome. The high polymorphism and heterozygosity, low mutation rate, and convenience for detection make STRs a kind of widely used genetic marker. The examination methods for STRs were also well developed. Today, STRs are applied to gene mapping, linkage analysis, genetic diagnosis and prenatal diagnosis, molecular anthropology, individual identification and paternity identification in forensic sciences, organic transplantation, etc
