Objective: According to the relevant policies of the state on the registration of adopted children, citizens are required to provide paternity test certificates when applying for adoption registration. In the process of actual paternity testing, it is found that some clients have the situation of "true birth and false adoption". In order to achieve the "bad" purpose of adopting relatives' children in the name of "abandoned babies", they often hide the real situation or provide false information. In the process of identification, the expert needs to analyze carefully. If there is a contradiction with the case, the expert can further communicate with the client, and increase the detection loci or Y-STR kits if necessary to avoid falling into the "preset trap" of the client. In addition, in the construction of related systems, still need to be further strengthened and improved.
