Secrets In Our DNA
Where to Watch
Some 30 million Americans have sent their DNA to be analyzed by companies like 23andMe and AncestryDNA, hoping to obtain clues to family origins and forecasts of their future health.

DNA results that offer estimates of health risks can be misleading, and the discovery of intimate family secrets can tear relationships apart.

What is the promise and peril of personal DNA?
