Our genetic makeup determines so much about who we are, and what we pass on to our children--from eye color, to height, to health, and even our longevity. Genetics 101 breaks down the science of how genes are inherited and passed from parents to offspring, what DNA is and how it works, how your DNA affects your health, and how you can use your personal genomics to find out more about who you are and where you come from.

Whether you're looking for a better scientific understanding of genetics, or looking into your own DNA, Genetics 101 is your go-to source to discover more about both yourself and your ancestry.
