Genealogical DNA test

Genealogical DNA tests are tests used to learn more about where you come from and how your family is connected. They are like puzzles that help you to build a family tree. The test looks at small pieces of your DNA, the molecules inside of our cells that make us who we are. These tiny pieces of your DNA can be compared to other people's DNA to see how you are related. With this technology, you can match with people who have the same ancestors as you, even if they live in other countries!
