Then they make their diagnosis. Also here is an exhibit about the GeneChip, a microchip covered with DNA probes that can be used to diagnose diseases. On a graphic panel inset with rotating trilons visitors read the stories of three people making decisions about genetic testing. Visitors can decide whether, under the same circumstances, they would undergo a genetic test. The cases include people deciding to be tested for sickle cell anemia, Huntington's disease, and cystic fibrosis.
Visitors find out what the real people decided and why.
Some of the difficult ethical issues surrounding genetic testing are explored. In this area visitors see real examples of bioengineering in plants and animals, and learn about the science and technology behind bioengineering and what changes scientists can already bring about. Then they decide if and when they would support using bioengineering to change plants, animals and humans, including themselves. Visitors see and examine living examples of animals and plants with new traits developed through breeding, mutations, and bioengineering. Examples include mutated and genetically engineered zebra fish, mice, and tobacco plants.
