Abstract: Abstract:Sex-chromosome STR(short tandem repeat), also called micro satellite DNA, as a special genetic marker plays important roles in parentage test and individual identification in forensic medicine. This article summarizes the conception, application, research progress and its limitation of STR on sex-chromosome in parentage test, in order to promote wider use of sex-chromosome STR loci in forensic science.
Key words: sex-chromosome STR; parentage test; individual identification
