Does more knowledge entail more responsibility?

Advances made by Human Genome Project raise a variety of ethical issues.

In your opinion, should partners who plan to be married and might have biological childrenbe obligated to inform each other of any known genetic problems that run in their family? Should partners have the right to request (or refuse to have) genetic testing prior to marriage? Provide reasons for your opinions. In discussing your position, consider genetic conditions that can be passed along to one's offspring, conditions that may affect the adult's functioning in the near or later future (e.g. some mental illnesses or neurocognitive disorders). You answer may vary depending on which genetic problem you are thinking about, so please specify.
