The prospect of designer babies, like many of the ethnical conundrumsposed by the genetic revolution, is confronting the world so rapidly that doctors, ethicists , religious leaders and politicians are just starting to grapple with the implications -- and trying to decide how they feel about it all.
They still have a bit of time. Aside from gender, the only traits they can now be iden-tified at the earliest stages of development are about a dozen of the most serious genetic diseases. Gene therapy in embryos is at least a few years away. And the gene or combination of genes responsible for most of our physical and mental attributes has not e-ven been identified yet. Besides, say clinicians, even if the techniques for making designer babies are perfected within the next decade, they should be applied in the service of disease prevention, not improving on nature.
