This blog provides information about DNA paternity testing and other types of DNA tests. Paternity Testing is now the most widely used method for confirming a biological relationship between an alleged parent and their child. The paternity test is normally performed through the analysis of the samples of the Mother, Child and Alleged Father. The test however, can also be performed without the sample of the mother. Results can also be conclusive this way.
A child will inherit half each of his DNA from both parents. The paternity test therefore analysis and compares the DNA of child to that of the parents to determine if they related. This is done by ‘matching’ specific points on the DNA called genetic markers to see if they are similar. For a paternity to be confirmed, all the loci need to match. When this occurs the paternity test will normally provide a result which confirms the paternity to a probability of 99.999% when the sample of the mother is included. If the loci do not match in all the regions, then the alleged father is excluded from being the father with a 100% accuracy rate. As one can see the DNA paternity test is a highly accurate test.
