The advancements in DNA testing have allowed scientists to answer many confusing questions. One of the best DNA test capabilities is to find out your ancestral roots, relationship, and much more. Additionally, with paternity testing, you can even confirm or rule out a person from the possible biological father list. Similarly, with genetic testing, you can even know who was your third great-grandmother. You can end your curiosity regarding your origins. There is also a face recognition app that can estimate whether you are related to someone or not.

For instance, you are looking at your DNA match list for the first time. It is generic how you are related to so many people. Additionally, an expert genealogist will look for how the matched groups are related to each other. Afterward, he will get to understand how they are related to you.

Understanding the matches:

In the picture below, you can see that Lisa took a DNA testing and got three matches, LP2345, Trevor Smith, and BH, who descended from LP2345, Trevor, BH, Mary Brown, and Jhon Smith. Additionally, each of them descended from a different child of Mary and John and are second cousins.

There are many methods available that can help you understand why you have a DNA match. There are many genetic testing service providers with a predicted relationship calculator. However, these are estimations that include half or removed relationships. The Shared cM project is a great tool that provides many relationship possibilities that are based on the cMs of two testers. With the help of these possibilities, we get to know that a second cousin or equal relationship is going to be the most likely relationship between Lisa and the other three testers; however other options are also possible.

For instance, let’s assume that Lisa is to be a grandchild of John Smith and Mary Brown’s daughter Lottie. Afterward, there were rumors that Lottie had a different father than other siblings, and now DNA can prove or disprove the theory regarding Lottie’s fatherhood. We can evaluate the shared matches to know if these matches include links to distant relatives of the John Smith family and also the linkage between relatives of the Mary Brown family. 

However, John Smith was an only child, and his parents were also only children. In this scenario, the closest relatives would be fifth cousins. If the candidate tester could be found, it can be very difficult to definitively confirm the connection to John’s family as many fifth cousins do not share DNA with each other. Now, what should be done to know whether Lisa is a full or half second cousin to LP2345, Trevor, and BH?

What are the odds DNA tool:

There is an online tool named WATO. This tool uses data from the Shared cM Project and probabilities of how one can relate to their matches. If the hypothesis has a possibility, it gets a positive score, while the other gets zero. You should also know that the score is more relative than to consider absolute. Now let’s try our theories. Let’s say Lottie was a full sibling with James, Robert, and Sarah. Now this means that Lisa is a full second cousin with LP2345, Trevor, and BH. On the other hand, let’s assume that Lottie was a half-sibling with James, Robert, and Sarah. This means that Lisa is a half-second cousin with LP2345, Trevor, and BH.

The last option on a WATO chart always has a score of 1, and other theories are scored according to their likelihood as compared with the score of 1. In our scenario, the second theory got a score of 1, while the first theory got a score of 166. This means that theory 1 is 166 times more to happen as compared to Hypothesis 2. 

Moreover, with Face DNA, you get the best DNA results that are reliable and authentic. Additionally, our DNA paternity testing can end your confusion regarding the fatherhood of your child. Furthermore, you can also get our face recognition app, which is quite helpful when you don’t want to spend any money. The application is also very reliable if you want to know if two persons are relatives.
