Some 30 million Americans have sent their DNA to
be analyzed by companies like 23andMe and AncestryDNA. But what happens
once the sample is in the hands of testing companies, and how accurate
are their results? NOVA explores the power of genetic data to reveal
family connections, ancestry, and health risks—and even solve criminal
cold cases.
