[DNA paternity testing]

At present, identification of the parent-child relationship was most of the DNA typing identification. Person's blood, hair, saliva, buccal cell, and so can be used for paternity testing, is very convenient.

A person has 23 pairs (46) chromosome, the same position on the same chromosome a gene known as alleles, a general from the father and one from the mother. If DNA testing to a site alleles, as a mother, father and another should be the same, otherwise there is questionable.

The use of DNA for paternity testing, as long as a dozen to a few dozen sites for DNA testing, if all the same, you can define the parent-child relationship, if there are more than three different sites, the parent-child relationship can be ruled out, 12-bit the difference, they should consider the possibility of gene mutations, and some of the sites to identify. DNA paternity testing, and negate the accuracy of the parent-child relationship almost 100 percent, certainly the accuracy of the parent-child relationship can be achieved 99.99%.

DNA paternity testing test FAQ

What is a DNA paternity test test?

DNA (deoxyribonucleic acid) is a physical body cells atomic material. Each atom has 46 chromosomes, while men's sperm and the woman's egg cell, and each has 23 chromosomes, the sperm and eggs of the time. This on chromosome 46 atoms to create a life, therefore, each inherited from the father half of the molecular substance, while the other half received from the mother.

DNA paternity testing test with the traditional blood tests are quite different. It can be conducted on a sample of different tests, including blood, gills cavity cells, tissue samples and semen samples. Because blood type, such as Type A, Type B, Type O or Type RH, in the population is relatively common, for the resolution of each individual, DNA paternity testing is not an effective test. Apart from the real twins, each person's DNA is unique. Because it is so unique, just like fingerprints, for paternity testing, DNA is the most effective method. Our results than is normally requested by the court also accurate from 10 to 100 times.
