The child\u2019s DNA profile is compared with the DNA profiles of the alleged father\u2019s biological parents. Since a child inherits half of their DNA from their mother (maternal) and half from their father (paternal), the paternal half should match DNA inherited from the alleged grandparents.<\/p><p>As in all relationship testing, the sample of a common parent (normally the mother) is always recommended.<\/p><p>DNA analysis of single grandparent: this test requires DNA samples from just ONE of the grandparents. The limitation of this test, however, is that a single grandparent shares only 25 % of their DNA with their grandchild. We strongly recommend adding the mother\u2019s sample in this particular case.<br \/>DNA analysis of both grandparents: We strongly recommended this test in which both the grandmother and grandfather are tested. The mother\u2019s DNA sample should also be included if available.<br \/>In both types of tests the DNA profiles analysed are compared with that of the grandchild to establish a biological relationship. The mother\u2019s samples are included to quickly eliminate her share of the DNA in the heredity process, which in turn leaves just the paternal half to test.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Home Service A grandparentage DNA test determines whether a couple could be biological grandparents of a child.
