With a simple and painless cheek swab you can sample your own DNA and submit it to the lab. We run ONE test per participation kit. We will test either your mitochondrial DNA, which is passed down each generation from mother to child and reveals your direct maternal ancestry; or your Y chromosome (males only), which is passed down from father to son and reveals your direct paternal ancestry. You choose which test you would like administered.
