Example Paternity Report - Inclusion (is the father)

This example of a DNA Worldwide Paternity Report shows the alleged father as "included" as the possible biological father. To be included, the Combined Parentage Index must be greater than 100 (the Probability of Paternity must be greater than 99%). DNA Testing Direct paternity probabilities regularly exceed 99.99%.

At each locus, matches between alleged father and child are identified. For each match a Parentage Index is calculated based on the frequency of the allele withing the population. If there are matches at all locations a Combined Parentage Index is calculated and a Probability of Paternity is generated. If these are significant mismatches (as few as 2 or more) the alleged father is 100% excluded as the biological father.

In this example, at locus D7S820 (highlighted), the mother and child share alleles measuring 9. Alleles measuring 12 are shared by the alleged father and child. Because an allele of 12 is relatively unique at this locus, the Parentage Index is 3.388.
