If you are passionate about genealogy you might have heard about DNA testing.
DNA is material that governs inheritance of eye color, hair color, stature, bone density and many other human and animal traits. Our body's cells each contain a complete sample of our DNA. As DNA is passed down from one generation to the next, some parts remain almost unchanged, while other parts change greatly. This creates an unbreakable link between generations and it can be of great help in reconstructing our family histories.
