The World's Premier Home Paternity Testing Service

Last week we talked about genetic reconstruction and its use in determining paternity and identifying family members. Aside from this extensive test, there are two other DNA tests through Beta that you can choose when traditional paternity testing is not an option.

Siblingship testing
When actors Liv Tyler and Mia Tyler met as children, they immediately recognized their physical similarities. The two knew that they had different mothers, but they had suspicions that they had the same father and were half-sisters.

To genetically determine their relationship, they could have undergone a siblingship test to determine if they were half-sisters. If the test revealed that they were half-sisters, then they could confidently say that they were both the daughters of Steven Tyler, lead singer of rock band Aerosmith.

Siblingship testing is best performed when DNA samples are collected from the two siblings and the siblings’ known parent(s) (in the case where the siblings know they have one different parent, both siblings’ known parents should be tested). Half-siblings will be those siblings that have genetic similarities with only one parent, while full-siblings will have genetic similarities with both parents. Because of its complexity, the siblingship test usually takes about 2 weeks to complete. To learn more about this test, visit our siblingship testing (http://www.betagenetics.com/siblingship-test.html) page now.

Grandparentage Testing
If Liv and Mia Tyler were unable to use siblingship testing, Liv could have considered grandparentage testing. This test would depend on the participation of Steven Tyler’s parents (Mia’s paternal grandparents) to submit their DNA for testing. Their DNA, compared to Liv’s and her mother’s DNA samples, would help identify a potential paternal relationship between Steven and Liv.

Generally, grandparentage testing includes DNA samples collected from a child, the child’s mother, and the alleged father’s parents. This test can be more complicated than a paternity tests, so the test requires more time to complete, with results typically released between 5 and 9 days. Visit our grandparentage testing page to learn more about this test.

If you are faced with the question of paternity, and the alleged father is unavailable, consider undergoing a siblingship test, grandparentage test, or genetic reconstruction.
