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.
With DNA paternity testing it is possible to 100% exclude someone as the biological father. However, the only way to produce a 100% positive result, would be to test the entire genome of an individual-all of their DNA. DNA paternity tests use a standardised sample of DNA-up to 15 DNA markers-to predict the probability of paternity. These probabilities are usually very high-as high as 99.9999%. This means that, for an alleged father who is not excluded, the paternity report is 99.9999% confident that he is the biological father.
