Appraisal parenthood

Appraisal parenthood currently use most of the DNA of identification. Is A person's blood, hair, saliva, oral cells can be used in parent-child etc., is very convenient. One of the 23 chromosomes (46), the same chromosome the same position as a pair of genetic alleles, usually one from the father, and from the mother. A If a DNA test to the site, a mother alleles, another can be the same with the father, or a question.
Using DNA in parent-child identification, just as ten to dozens of DNA test, if all sites, can be used to determine if a child, above 3 different sites, exclude parenthood, one or two different sites, should consider the gene mutations can do some sites, plus the check. DNA parent-child relationship, the accuracy of negation parent-child relationship, nearly 100% accuracy of the child reaches got.
DNA tests of common problem child identification
What is the child of DNA tests identified?
DNA (deoxyribonucleic acid) is personal cells in the body of the atomic matter. Each atom is 46 chromosomes, in addition, men and women's eggs sperm cells, each with 23 chromosomes, when sperm and egg combination. This 46 atomic chromosome is a life, therefore, each from his inherited half of molecules, and the other half from birth place.
DNA parent-child appraisal test and the traditional blood test is quite different. It may be in different samples, including blood tests on the cheek, cells, tissue cells cavity sample and semen samples. Due to blood types, such as A type, type B, type O or RH type, in the crowd, used to distinguish comparison of every man, but not valid identification of DNA tests child. Besides, the real twins each DNA is unique because it is so unique. Like fingerprint identification, child, used to be the most effective method of DNA. Our results are usually required than court accurate 10 to 100 times.
The identification of the parent accuracy
DNA parent-child appraisal is the most accurate identification method, if the child QinQuan genetic loci and tested the man (at least 1) sites, so the man inconsistent and 100% excluded, namely consanguinity absolutely impossible, he is the father of the child. If children and parents are the sites, we can draw the possibility of greater QinQuan relations, namely that got the kinship relations between them kiss.
Parent: (1) was identified notice shall be designated by the mother - the son - suspicious father or the parents and children - father or mother only two people generally not accepting JianDingZhe, (2) per adult consent to be identified, 12 years of teenagers should be appropriate to the identification of the opinion, (3) by expert should know his near relatives or any genetic history, (4) age generally identified children aged in half as well, (5) amniotic fluid or fluffy for pregnant women and suspected child appraisal shall be signed by identifying the father aggrement.
