[Identification of sibling brothers using STR and Y-biallelic markers].

Objective: To explore the methods for identification of sibling brothers with Y-STR locus mutation by detection of genetic markers on autosome and Y-biallelic.

Methods: Goldeneye 20A and 18NC kit were used to genotyped the 35 STRs on autosome from two men. PowerPlex Y kit and Yfiler kit were used to genotyped the 16 STRs on Y chromosome full sibling index was calculated by ITO method.
