You can learn more about these “non-standard” DNA samples by clicking on Alternative DNA Samples, or call us a 1-855-362-5224.
It depends. Since half siblings share 25% of the same DNA, and first cousins share 12.5%. Depending on if a mother’s DNA is available to test as well, there may be other testing options that would give stronger results. In these situations we encourage you to talk with one of our Genetic Consultants at 1-855-362-5224, …
