We all inherit our DNA from our biological parents â half from our mother and half from our father. A DNA paternity test compares a childâs DNA pattern with that of the assumed father to determine if there is a match.
DNA testing is the most accurate method available for determining paternity. Its power lies in the ability to trace the pattern of inheritance for separate regions of the genetic material (chromosomes). From this information a probability of paternity can be calculated. This number can reach 99.99999% in some cases.
