Abstract:
Objective To identify the half-sibling relationship by comprehensive using three different methods. Methods STR genotype was performed on A, A's mother, B and B's mother by using PowerPlex21 kit, AGCU Expressmarker 21+1 kit, Microreader 23sp-B kit and AGCU X-19 STR kit respectively. Based on the results of STR genotype and X-STR, we determined half-sibling relationship by ITO, discriminant function analysis and IBS. Results HIS was between 1.36×102and 2.09×105in ITO which indicated that A and B had the same father. The IBS and discriminant function analysis also had the same conclusion. Conclusion Comprehensive using multiple methods can obtain reliable result to identify the half-sibling relationship from the same father.
