Description

This program gives an explanation of the promises and the dangers inherent in deciphering the gene map, and a warning about the dangers of eliminating genetic variation and recessive traits. The program analyzes the potential misuse of genetic information and demonstrates the potential of genetic engineering to provide the first true preventive medicine program in medical history, as well as the possibility of eradicating single-gene defects like thalassemia; it also explains the dangers of narrowing the genetic pool, and-in a segment with extraordinary photography-shows the injection of human genes into mouse ova so that they merge with the mouse DNA. And the program proceeds to ask: Is this the first step to wiping out genetic illness-or to wiping out ourselves?
