This is the homepage of a PBS documentary about genetic technologies that was first aired in June 2003. The Web site has many online-only interactive features, including a section called Fact or Fiction. Here users can test their knowledge of reproductive technologies, cloning, legal DNA issues, and other topics. Stem cell research is outlined in one of the parts of Mapping the Future, and ethical considerations are the focus of Drawing the Line. An extremely detailed timeline of genetic technologies traces notable events and discoveries back hundreds of years.
