Grandparentage Legal

A Grandpaternity DNA Test, also called a Grandparentage Test, compares the DNA from a child to his or her biological mother, as well as at least one biological paternal grandparent.  Since the alleged father inherited 1/2 of his DNA from his mother (grandmother) and 1/2 of his DNA from his father (grandfather), it is always preferable to include both biological grandparents in this type of DNA family relationship test.

Test Details

This test will reflect the probability of relationship.  A “0” means there is no biological relationship.

If the grandparentage index is greater than 1.00, this indicates that the tested individuals are more likely to be the true biological relatives.  The higher the value of the index, the greater the likelihood that the individuals are true biological relatives.

If the grandparentage index is less than 1.00, this indicates likelihood of non-relatedness.

**Note:  If both biological grandparents and the child’s mother are not included in the DNA Grandpaternity Test, the test results may not always be conclusive.
