A grandparentage test is often one of the better relationship tests to perform to determine paternity of a child. The best testing scenario is a test which includes the mother, child and both of the alleged father’s parents (the child’s paternal grandmother and grandfather). By including both of the alleged father’s parents, the alleged father’s DNA profile can be reconstructed. Comparing the alleged father’s reconstructed profile against the child’s DNA, can allow this testing scenario to give results as accurate as a paternity test. Each time a person is removed from the test, such as a grandparent or mother, the strength of the genetic evidence decreases, therefore testing all 4 individuals is the best testing option.
