经遗传学或血液检验所得到的资料常用于解决亲权的争议。在一个孩子身上所发现的表型因子不仅仅来自其母也来自其父,而且在这一孩子的专性因子中有一部分是由生父遗传基因所组成,如男性缺少任何专性因子,表明他不是生父(可被排除),反之,如含所有专性因子并符合所描述的遗传特征,则不能排除是这一孩子生父的可能性。然而,单凭这一点是不能作为亲权证据的,因其他男性也有可能符合所描述的遗传特征。如果被指控者是亲生父亲,那实际上就属所估计的概率了,这种估计是根据大群体 Data obtained through genetic or blood tests are often used to resolve parental disputes. The phenotypic factors found in a child come not only from their mother but also from their father, and part of this child’s obligate factor is composed of the father’s genetic elements, such as the lack of any obligate factor in men, indicating that he Not a biological father (which can be excluded). Conversely, if all the obligatory factors are included and the described genetic characteristics are consistent, then the possibility of having a biological father can not be ruled out. However, this alone can not be taken as evidence of paternity, as other males may also be able to meet the described genetic traits. If the accused is a biological father, then it is in fact the probability of being estimated, this estimate is based on large groups
