摘要: 目的 介绍计算叔侄指数的方法。 方法 常染色体STR基因座鉴定争议叔与孩子的叔侄关系,用引入血缘一致性系数法、引入共祖系数法和AI定律计算叔侄指数。 结果 引入血缘一致性系数法、引入共祖系数法以及AI定律计算叔侄指数的结果一致。 结论 不同情形下3种方法计算叔侄指数的结果一致,孩子母亲参与鉴定计算所得的叔侄指数往往比孩子母亲不参加鉴定的叔侄指数高。

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.
