While most DNA paternity tests reflect our 'text book' example, there are many other factors to be considered. For example, natural mutations sometimes present more complicated results. Sometimes father and child share many common alleles and though there are many matches, the CPI value is not strong enough for a conclusive result. In most of these cases, including the biological mother significantly strengthens the test results. That's why IDENTIGENE strongly recommends including the mother on any DNA paternity tests.
Including the biological mother in any DNA paternity test strengthens test results. Whenever possible the mother should submit DNA samples as a participant. Testing the mother's DNA increases the likelihood of a conclusive result for any DNA test - including DNA tests for paternity, siblings, or grandparents.
