Genetic Reconstruction

A grandparentage DNA test determines whether a couple could be the biological grandparents of a child. It is an indirect way to determine family relationships when an alleged father is not available for a paternity test. Grandparentage test results may be used as proof in Social Security benefit and other inheritance claims as well as in some immigration cases.

 

In the test, the child’s DNA profile is compared with the DNA profiles of the alleged father’s biological parents. Since a child inherits half of his/her DNA from the mother (maternal side) and half from the father (paternal side), the paternal half should match DNA passed down from the alleged grandparents. The mother’s participation is encouraged to expedite analysis; motherless grandparentage tests take longer to complete because of the extended analysis required.

 
Avunculer

An avuncular test is done to determine if a child is biologically related to a sibling of the alleged father. This test is a good option when there are no samples for a deceased AF or he is unwilling to test and the only relative available is a single sibling, brother or sister of the AF.

 

  • The report will indicate the probability of relatedness and a liklihood ratio similar to a reconstruction report. Refer to the relationship page.
  • The limitation of this test is that an uncle/aunt shares only 25% of their DNA with a nephew/niece. Since DNA is randomly inherited from our parents, siblings may or may not share significant amounts of DNA from their parents.
  • We strongly encourage the mother to participate so we can account for one half of the child's genetic material and provide a more precise result.
  • Inquire if other siblings of the alleged parent are available for testing. This will result in a reconstruction and the potential to more accurately ascertain the alleged relationship.
  • In scenarios with limited relatives to test investigate the possibility of utilizing Y-STR, X-STR or Mt-DNA testing as well.
