DNA grandparentage testing is used to establish a genetic family relationship between a possible grandparent and grandchild or to establish paternity if the child's alleged father is not available for testing.While it's true you get ~25% of your DNA from each grandparent, the exact fraction that we receive from our grandparents is governed by chance.
