As the popularity of genetic tests like 23 and Me grows, so does the possibility of learning something completely foreign about yourself and your ancestry. But not all news is good news. Journalist Libby Copeland talks about how some of these discoveries in genetic makeup are unveiling complicated family secrets and changing some people's sense of self. She talks about one family's story she writes about for The Washington Post. Copeland explains that there are two common findings for people using these tests. One is that you might find out that you have a sibling or half-sibling that you didn't know, or the other is that may find out you were raised by someone who is not your biological family. Plus, listeners call in with their personal stories about using a home DNA test and uncovering surprising information.
