用数种血型系统鉴定亲权关系未能予以排除时,往往需要进行父权肯定机率的运算,以明确“父子”间有多大的相似度(The Iikelihood of paternity)。此项计算比较复杂,且我国尚无赖以计算的标准数据。本文根据国内调查资料计算出中国汉族13种血型系统的父权肯定机率,供亲权鉴定时参考。 When identifying the relationship of parental authority with several blood group systems, it is often necessary to determine the probability of paternity to determine the degree of similarity between the “father and son” (The Iikelihood of paternity). This calculation is more complicated, and our country still has no standard data to be calculated. Based on the domestic survey data, this paper calculates the probability of paternity affirmation of 13 Han Chinese blood group systems for the reference of paternity testing.
