Chances are you or a family member has undergone a genetic data analysis through one of the many DNA analysis services. Reports estimate that more than 26 million people have shared their DNA with one of the four leading ancestry and health databases. The results can be interesting and informative, but there are some far-reaching implications.

Perhaps you have heard the stories—or know someone personally—who found an unknown sibling or learned their parents are not their biological parents. DNA analysis services have been used to assist law enforcement with criminal cases. There is also the issue of what happens to that genetic material after you die.
