Extended data

At present, DNA typing is the most commonly used method to identify parent-child relationship. Human blood, hair, saliva, oral cells and bones can all be used for paternity testing.

Using DNA for paternity testing, as long as ten to dozens of DNA loci are detected, if they are all the same, the paternity can be determined; If more than three loci are different, the parent-child relationship can be ruled out; If one or two loci are different, we should consider the possibility of gene mutation and detect some loci to distinguish them.

In DNA paternity, the accuracy of denying parent-child relationship is nearly 1 0,000%, and the accuracy of affirming parent-child relationship can reach 99.99%.
