Abstract:
OBJECTIVE:To introduce the method of avuncular index (AI) calculation.
METHODS:Identity by decent coefficient, coancestry coefficient and AI law were employed in identification of uncle-niece relationship, when autosomal STR loci were detected to determine controversial uncle-niece relationship.
RESULTS:The results of AI calculation were coincidental using identity by descent coefficien, coancestry coefficient and AI law.
CONCLUSION:The results are coincidental using three methods in the different situations. AI index is higher with participation of children's mother.
