Grandparentage DNA test:
This test helps grandparents to verify their genetic connection with their grandchild. This test determines that the grandchildren have a biological relationship with their grandparents the Grandparentage DNA test.
Under the Grandparentage test you get two options:
Single grandparent DNA analysis:
This test only involves one grandparent. It can be a grandfather’s or a grandmother’s DNA test. In this kind of case, you might need the mother’s sample to enhance the results. Although checking with only one grandparent and a parent may yield conclusive results. There is always the possibility of inconclusive results.
DNA analysis of two grandparents:
In this test, both the grandfather and grandmother are present to do this test. The mother’s sample is not required for testing. To determine the likelihood of a biological relationship you need some samples. The samples include the Genetic material of grandparents and the DNA of the grandchild.
Then the experts compare the DNA sample of grandparents and grandchild. On the bases of the results, they determine the biological relationship.
Why Duo Grandparentage DNA test is better?
We can do 2 things in a duo grandparent test. First, we use the DNA of the grandfather and grandmother to recreate the DNA of the unknown, absent parent. Now that we have the DNA profile, we can determine the child’s fatherhood or maternity. Experts do this by correlating this DNA to the child’s profile. This verifies whether the absent, parent is the child’s biological parent. You can use this test to get the possibility of a connection between grandfather and grandchild. Or between grandmother and grandchild in a grandparentage DNA test.
