Aunt/ Uncle
Avuncular DNA testing involves comparing the DNA of an aunt or uncle with a niece or nephew to determine the statistical probability of a biological relationship. This test is useful for indirectly establishing paternity or maternity when the alleged father or mother is unavailable for a paternity or maternity test. For optimal results, the avuncular test is most effective with the alleged parent’s full sibling (brother or sister) who shares the same mother and father. Performing the test with the alleged father’s half-sibling may increase the risk of weak or inaccurate conclusions.
