Scientists have learned a lot about how genes can cause disease. Maybe one day scientists will be able to remove a gene that causes a defect and replace it with a "normal" gene. They can already do this for some genes. How nice would it be to remove the defective genes and cure diseases and disorders such as Cystic Fibrosis, Down Syndrome, Sickle Cell Anemia, etc.? Some people also think that it would be great to determine the eye color, height, gender, hair color, and other traits of their offspring. What should we use our knowledge of genetic information to control? Should we cure diseases? Is dying from a genetic disorder a natural process of life? Should we be able to form "designer babies"?
