Objective: To observe the mutational pattern of STR loci in parentage testing cases.
前言：目的：观察亲子鉴定中str基因座的突变方式。
Results: in 30 cases of parentage testing, 11 cases (36.67%) were excluded from parent-child relation.
结果：在30例三联体亲子鉴定案例中，排除亲生关系11例，占36.67%。
Methods Based on the law of inheritance and allele frequency, the powers of exclusion of STR loci in motherless parentage testing (PEM) were calculated.
方法根据基因频率和遗传规律，推导单亲案亲权鉴定时的非父排除率。
