DNA paternity test

Identification of parent-child relations are the most use of DNA typing is identified. People's blood, hair, saliva, oral cells can be used by all paternity testing, is very convenient. A person has 23 pairs (46) chromosome, the same position on the same chromosome a gene called alleles, a general from his father and one from the mother. If a DNA test to the site of the allele, the same as a mother, father and another should be the same, otherwise there is a doubt. The use of DNA for paternity testing, as long as a few dozen to a dozen sites for DNA testing, if all the same, we can determine the parent-child relationship, if there are more than three different sites, parent-child relationship can be ruled out, there are 12-bit Different point, it should consider the possibility of gene mutations, and do some testing sites to identify. DNA paternity testing, the negative parent-child relationship of nearly 100 percent accuracy rate, certainly the accuracy of the parent-child relationship can be reached 99.99 percent. DNA paternity test test FAQ What is a DNA paternity test test » DNA (deoxyribonucleic acid) is the physical body of the atomic material. Each atom has 46 chromosomes, while men and women of the sperm cells and eggs, and each has 23 chromosomes, when the sperm and egg combination of time. This 46 atoms to create a life on the chromosome, each from a father who inherited half of the material elements, while the other half from the mother was. DNA paternity testing testing with the traditional blood tests are quite different. It can be in different tests on the samples, including blood, gills cavity cell, tissue samples and semen samples. Because blood type, such as Type A, B-, O-or-RH, the crowd in the use of more common, used to identify each individual's blood relationship, but as DNA paternity testing testing effective. In addition to the real twins, each person's DNA is unique. Because it is so unique, like fingerprints, for paternity testing, DNA is the most effective method. We are usually the result than the requirements of the court also accurate from 10 to 100 times.
