Where is the human body taken for paternity identification on the household registration?

Samples of individual paternity testing (blood, hair, saliva, etc.) can be taken by themselves and sent to a professional appraisal agency, and the results of the appraisal will only be provided to the appraisal client.

In the sampling process, personal appraisal does not require a power of attorney issued by the public procuratorate, procuratorate, and law, nor does it completely require the applicant to provide ID cards and other documents and consent forms, which is only used as a voucher for the appraiser's parental authority appraisal and can be used as one of the evidence, but the accuracy of the appraisal process and appraisal results is consistent with the judicial appraisal.

Paternity testing involves extracting DNA from tissues such as blood, hair, and oral exfoliated cells of a parent, and then sequencing after extraction. A person has 23 pairs (46) of chromosomes, and a pair of genes in the same location on the same pair of chromosomes is called an allele, one from the father and one from the mother.

If an allele of a certain DNA locus is detected, one is the same as the mother, the other should be the same as the father, otherwise there is a question. At this stage, a special DNA locus is commonly used in paternity testing, the STR locus.

For example, in one case, a child's STR numbered FGA has 22 and 25 repeats on both chromosomes from the parents, labeled FGA-22 25. If the mother is FGA-22 type 23, the comparison can determine that at least one allele of the paternal gene is FGA-25.

However, in the population, there are many males containing the FGA-25 allele, and there is a certain probability of mutation in the STR locus, so the testing agency will use multiple loci for testing, which will greatly reduce the probability of error in judgment.

In forensic testing in the United States, 20 loci are generally used, compared to 17 in the United Kingdom.

The triad genetic test (father, mother, child) in our country is generally 16 STR loci, and if 1 contradictory locus is found, it will increase to 19 loci; If 2 contradictory loci are found, this increases to 28 loci; If 3 contradictory loci are found, the number of loci will be increased to 35 or more, and if 4 contradictory loci are present, the conclusion of "non-biological relationship" will be directly made.

The paternity test is carried out by DNA sequencing comparison, and in principle, any part of the human body can be sampled from which the chromosomes can be extracted. The more common ones are the extraction of blood specimens, oral mucosal epithelial cell specimens, etc.

Personally, I think that in general, saliva or blood is collected.

Generally, a paternity test is done to take blood, but hair is also acceptable.

Hair and blood for an identification report.

Summary. Hello, glad to answer for you! How to do a paternity test only for the father's household registration book:

Paternity testing refers to the use of theories and techniques of biology, genetics and related disciplines to determine whether the parent and child of the accused parent are biological according to the inheritance law of genetic traits between offspring and parents. Additional Information:1

If one parent is genetically homozygous, all offspring carry the gene. The most commonly used method in paternity testing is blood typing, in which all blood group systems (red blood cell blood group, white blood cell blood group, serotype, red blood cell enzyme type) are passed from parent to offspring according to Mendelian inheritance rules.

There is no mother's information, only father's information, how to give the child a household registration book.

How to replace the birth certificate without a birth certificate: 1. For persons without hukou who were born in midwifery institutions, they or their guardians can apply for a "birth medical certificate" from the midwifery institution 2. For persons without hukou who were born outside the midwifery institution, they or their guardians need to provide a paternity certificate issued by a qualified appraisal agency and apply for a "birth medical certificate" from the agency entrusted by the county-level health and family planning administrative department of the place where they are to be settled. 2. The child does not know who the father is an illegitimate child, and the information required for the illegitimate child to register the household registration:

1. Birth Declaration and Registration Form; 2. Medical Certificate of Birth; Zheng Stuffy orange 3, the "Resident Household Booklet" of the settled party; If the settlement party is a collective household or a public address or a demolition address, it must provide a commitment that the settlement party and his or her spouse have no housing in the city; 4. "Confirmation of the Ethnic Composition of the New Population" (if the ethnic composition of the parents is not the same, if the ethnic composition is not the party where the settlement is accompanied, the written opinion of both parents must be provided to confirm the declaration of ethnic composition); 5. The above materials of the "Statement" (signature and fingerprint) of the settled party for non-marital birth of children shall be provided in original form for verification, and if the materials provided by the police station outside the province are involved, they shall be stamped with the special seal of the police station. The father (mother) of a child born out of wedlock shall apply to the police station where the household registration is located, and the materials shall be complete and there is no reason for the investigation, and the application shall be completed on the spot.

I believe many people have heard of paternity testing, but few people will do this kind of identification, because what is done is to confirm the blood relationship with relatives, unless there is a special reason to do it, and some need to do a paternity test because of the child's household registration. So, does a child need a paternity test for the father?

Not all children have to do a paternity test when they are registered, and the circumstances of doing a paternity test when they are registered are:

1. No birth certificate. Due to various reasons, the child was not born in a hospital with obstetrics and gynecology qualifications, or was not born in a hospital, so there is no standardized birth certificate, and a paternity test is required when registering. or have a birth certificate, but the name of the parents on the birth certificate is inconsistent with the name on the ID card and household registration book, and a paternity test certificate is required.

2. Because the child is abducted or lost, and later recovered through various channels, the household registration needs to be with the biological parents, and the paternity test report is required. 3. If the child is born out of wedlock, the existing legal documents cannot prove the biological parental relationship of the child. or in single-parent families, the child's household registration needs to be transferred from the father to the mother, or from the mother to the father, and a paternity test is required.

4. The abandoned child goes home to the house. If the child is taken out and needs to be adopted, or because of the evasion of family planning, the child's household registration needs to be transferred to the name of the biological parents in the name of another person, and a paternity test is required. 5. Special provisions of the department, because some departments are afraid that other industry personnel will enter the special industry when recruiting workers and cadres, they need to make proof of parent-child relationship between parents and children in the industry when recruiting workers and cadres.

For example, the Zhengzhou railway system recruits workers, and a paternity test certificate is required. 6. When an adopted child goes to the household, it is necessary to prove that the child and the adoptive parents are not biological.

Paternity testing is based on the genetic law of DNA, to determine the relationship of a test method, in the current paternity testing two ways, one is invasive paternity testing, the other is non-invasive paternity testing. Invasive paternity testing is to obtain the genetic information DNA of the fetus in the amniotic fluid through the method of amniocentesis, and then determine the genetic relationship according to the DNA information. Non-invasive paternity testing is to take the peripheral blood around the pregnant woman, obtain the DNA information of the fetus from the peripheral blood, and then amplify, and then determine the parentage through DNA comparison after amplification.

At present, non-invasive paternity testing is widely used, and there are more institutions doing non-invasive paternity testing in the society. These are the two common methods of paternity testing.

DNA paternity tests are very different from them. Even before the child is born, without the participation of the mother, and it is the most accurate kind of paternity test at present - the accuracy rate is reachable, so it has the characteristics of exquisiteness, simplicity, speed, economy and practicality.

It depends on your specific situation and the requirements of the local police station. For example, if the mother is gone, there is only the father and the child, and the father-daughter identification is no problem. If the mother is there, and the police station requires the mother to participate in the evaluation as well, it is best for the three of them to do the evaluation together.

In addition, the paternity test belongs to the scope of forensic authentication and must be conducted in a formal local forensic institution to be valid. For details, please consult the local judicial bureau or the provincial judicial department.
