Genetic knowledge, its nature and proper use is a controversial issue in bioethics. Developments in biology are making it increasingly possible to acquire information concerning our genetic makeup. For the time being the benefits are felt mainly in fetal diagnostics. However, it is predicted that, along with the completed Human Genome Project, genetics will change the entire field of medicine as we know it. The improved treatments, diagnostics, and medications are expected to reduce and prevent unnecessary suffering considerably. On the other hand, the very existence of genetic information has raised moral questions and caused distress. It is felt that knowledge of DNA, of the 'secrets of life," poses a threat to our conception of ourselves as individuals and persons. Can we save the concept of "a soul"? What happens to the free will? Is everything determined?
