In this article, the author reviews "Roche Genetics: Education Program" CD-ROM version 4.0. The program is organized using a theme park analogy. An information booth leads to a central area connecting paths between five park areas. Topics include basic genetics, methods for studying monogenic and common complex disorders, pharmacogenetics, and a discussion of common questions concerning the ethics of research in such areas.
