Every individual person has their own unique DNA fingerprint, which includes markers that come from each parent. These markers are called microsatellites. This technology can conclusively verify the biological parents of each individual. DNA paternity test utilizes thirteen different microsatellite markers to reduce the possibility of error to virtually zero. For simplicity, the data is depicted for only one microsatellite marker.
Larger pieces are at the top, and smaller pieces are at the bottom.
Each person has two copies of the marker, so there are two PCR products. This copy of the marker was passed on from mother to child. Maternity Testing Maternity testing is performed to determine the biological mother of a child. The DNA testing technology and the accuracy of test results is same for maternity testing as explained above for paternity testing. All you need to do is contact us by e-mail or telephone.
