Basically, the saliva you send them includes multiple cell sources that provide clues to your ancestry. For example, a single saliva sample will contain epithelial cells from the inside of your cheeks, as well as white blood cells from your saliva. Both contain your DNA, which carries a history of human migrations and origins. 23andMe compares your DNA to the DNA of individuals in different parts of the world, then maps your genetic ancestry based on similarities.
The process is simple -- they send you a kit, you spit in a tube, you send said tube back to their lab for testing. Once there, they isolate the DNA and analyze it for markers related to health, ancestry, traits and more -- depending on which services you’ve selected. What you get is extensive: it includes over 75 reports on topics like lactose intolerance, muscle composition, and sleep quality.
