The registered permanent residence belongs to judicial expertise.

Paternity test, also known as paternity test and paternity test, is a forensic living test to judge whether there is a biological relationship between disputed parents and children by using the theories and technologies of medicine, biology and genetics according to separation phenomenon inherited by Mendel.

Paternity test mostly needs to be carried out under the following circumstances:

1, unmarried pregnancy or family disputes suspect that the child is not biological;

2. Identify long-lost family members;

3. Inheritance should determine the biological relationship or the parent-child relationship of IVF;

4. Suspect that the hospital has improperly adjusted the newborn baby;

5. Suspected of evading the family planning policy, adopting one's own children as adopted children or raising super-born children to others;

6. Immigration notarization needs to determine whether immigrants are required to be related to someone.

Methods of paternity test:

1. The traditional paternity test is blood type test. Generally, children can only do it for more than 6 months, and they need a lot of blood samples. This method has complicated process, painful sampling and high error rate. Traditional blood type judgment has its role to some extent, but paternity test can not be based on blood type.

2.DNA paternity. DNA paternity is taken from any tissue of human body (such as oral epithelial cells), and can also be performed before the baby is born. This method is the most accurate one in the parent-child test at present-the accuracy rate can reach 99.99999%, and it is exquisite, simple, fast, economical and practical. According to the practice of paternity test at home and abroad, when the RCP value is greater than 99.73%, it can be considered that the father and the child have a biological relationship.

3.SNP detection. At present, DNA paternity uses the repeated base sequence in human genome (STR as the second generation molecular marker) and PCR technology to identify individuals, but STR has great limitations. SNP is the third generation molecular marker technology, which is the future development direction. It is used for corpse identification in the United States 9 1 1.
