Genetic genealogy

Genetic genealogy is a way of tracing your family tree using science. You can find out things about your ancestors and their families by looking at your DNA. DNA is a code that is unique to you; it’s like a fingerprint that you get from your parents. A DNA test will show the parts of your parent's DNA that you got from them, which can help you learn about your ancestors. You can find out what parts of the world your ancestors came from and even who some of your distant relatives might be. The more of your family you have tested, the more you can learn about your family tree!
