Grandparent DNA Test

A grandparent DNA test, sometimes referred to as Grandpaternity tests,  allow the parent or parents of the alleged father, or mother in some cases, to participate in a DNA test. A Grandparent DNA test will determine if the alleged paternal grandparents are the biological grandparents of the suspected grandchild through either the father or mother. A Grandparent DNA test can be performed with either one or both of the grandparents, but including both grandparents (from the same family) sometimes offers a stronger result. If the grandparent’s doing the DNA test wish to verify the paternity of the child, and are able to include the biological mother, the result will be the same as if a paternity test was taken with the father and child. If the biological mother is not available, the test can still be performed.

How Grandparent Testing Works

Children inherit 50% of their genes from their mother and 50% from their father so the children would share 25% of their DNA with each biological grandparent through heredity.  In a grandparent DNA test taken as an alternate method of determining paternity we are trying to determine if the DNA from the alleged grandparent or grandparents have matching DNA that could be inherited from the biological mother or father. For example: if the paternal grandparents are tested and they do not have matching DNA genetic markers between them and the alleged grandchild then they would be excluded as the biological grandparents and the probability of grandparentage will be 0%.  If the paternal grandparents are tested and they share matching DNA genetic markers between them and the alleged grandchild then cannot be ruled out as the biological grandparents and the probability of grand-parentage will be more that 99%.
