[The evaluation of 12 STR loci genetic polymorphism in Han population].
OBJECTIVE
To investigate the genetic polymorphism of 12 STR loci in 240 Han population and evaluate application of the 12 STR loci systems in forensic cases.


METHODS
12 STR loci were amplified with Muti-loci STR PCR system, which were genotyped with electrophoresis separation on dPAGE.


RESULTS
12 STR loci system had high power of discrimination (DP) and it was suited for analysis of dated bloodstain especially.


CONCLUSIONS
The 12 STR loci systems is simple economy and practicality, which is useful in forensic identification and disputed paternity.
