23andMe might just be the most popular brand of at-home DNA testing on the market, for good reason. It will let you know what your ancestral composition is out of more than 1,500 regions, trace the origins of your maternal and paternal lines, figure out when new ancestries were introduced to your DNA, and how many generations ago you had an ancestor that came from a single population. You can also opt-in to the relatives tool, which lets you see who else shares your DNA across 23andMe users. While the recorded number of users is smaller than AncestryDNA (5 million as opposed to 10 million), you will still get compare traits and connect with a whole host of potential family members. Plus, you will get a comprehensive report on common traits you might have based on your genetic makeup. You might finally know why you have freckles when the rest of your immediate family is freckle-free.
