A grand parentage DNA test determines whether a couple could be the biological grandparents of a child. In the test, the child’s DNA profile is compared with the DNA profiles of the tribal member’s biological parents. Since a child inherits half of his/her DNA from the mother (maternal side) and half from the father (paternal side), the half contributed by the family member in question should match DNA passed down from the tested grandparents.
Who needs to be tested? One Mother, one Child, and both Paternal Parents (Mother and Father of the Alleged Father)
