In cases where the alleged father is not available to participate in DNA testing (for example he is deceased or unwilling to participate), the parents of the alleged father can participate to find out if they are the true biological grandparents of the child. When conducting a grandparentage DNA test, it is recommended to test both grandparents (the grandmother and the grandfather) in order to obtain the most conclusive results. If this is not possible, a grandparentage test can be conducted by testing only one grandparent. The participation of a common parent (normally the Mother) is also recommended to strengthen the results.
DNA is passed down from grandparents to their children and then again passed down when those children become parents. This is what geneticists call heredity; the term itself referring to how we inherit our DNA from our parents and pass it on as generations roll by. Hence, by using the DNA of the alleged father’s parents it is possible to reconstruct the father’s genetic profile.
Two Types of Grand-Parentage Tests Offered Order Here
Single grandparent DNA analysis: This is the less recommended of the two and should be the chosen test only when one grandparent is available for testing. The mother’s DNA should also be given for analysis in order to corroborate the results.
Duo grandparent DNA analysis: This is the better of the two options and involves testing both grandparents. Testing the mother’s DNA is also often part of the test though not a necessity. Normally, the mother’s genetic blueprint makes the test more discriminating by eliminating her share of shared genetic material.
The Grandparentage DNA test starts from $495 for one grandparent and grandchild. Your results will be sent to you within 5-7 working days from when we receive the samples at the laboratory. Contact us if you want to discuss any relationship DNA test you require.
