Did you know that you may be able to gain answers about paternity if the alleged father is unavailable?

Other DNA tests are an option if you cannot undergo a standard paternity test. The most common non-paternity DNA tests for learning more about paternity are grandparentage, siblingship, and genetic reconstruction.

For circumstances where the alleged father’s parents are available, grandparentage DNA testing can be used to help answer questions surrounding paternity. In a grandparentage test, a child’s DNA profile is compared to the mother’s and the alleged father’s parents’ (potentially the child’s paternal grandparents) DNA profiles. The child’s relationship to the alleged father may be better understood if the child’s profile matched the alleged father’s parents’ profiles. However, this match could also be the case if the alleged father’s biological brother were the child’s father.

Siblingship DNA tests can be used when two people believe they share the same biological parents. If two siblings share the same mother, they can use a siblingship test to determine if they also share the same father (and are thus full siblings). Their DNA profiles will be compared to see if they have biological information from the same two parents or only one parent, their mother (if the two have no genetic similarities, the likelihood for them being biologically related is low).

Finally, genetic reconstruction is a more complex DNA test for determining paternity relationships. The DNA profile of the child and the child’s mother will be compared to the profiles of at least two close relatives, such as a full sibling or a biological parent, of the alleged father. If the child’s profile is similar to the profiles of the alleged father’s close relatives, then paternity may be inferred. However, because this test is complicated, it may take more extended DNA testing to definitively determine paternity.
