Missing / Deceased Father? Try a Grandparentage Test
When a father is available for sampling the usual DNA Paternity test may be performed. However when a father is deceased or otherwise not available for testing, a DNA Grand-Parentage Test may be performed using the father’s parents to establish the child’s paternity. This test will determine whether the tested couple’s child fathered the tested child by establishing biological relationship between the child and the alleged grandparents
For the grandparent’s test the child’s DNA profile is compared with the DNA profiles of the alleged father’s biological parents. Because a child gets half of his or her DNA from its mother and half from its father, the paternal half should match the DNA passed from the alleged grandparents to their child and thus to the tested child. The fastest analysis may be performed when the child’s mother participates in the testing; however, a motherless grandparentage test (does not include the child’s actual mother) takes a longer time to process as extended testing becomes necessary.
A grandparentage test may be need to establish biological relationship in some immigration cases, to establish Social Security benefits and in claims of inheritance matters. The maternity DNA test as well as the paternity DNA test is also fast becoming the norm in immigration cases that claim a biological relationship. For nearly every purpose, there is a DNA test which may be done to prove or disprove a point, see some of the other DNA tests that the technology now offers.
