This book explores the many prospects, challenges and ethical questions of engineering our reproductive cells. It is an accessible, three-part examination, moving from focused, realistic assessments of the possibilities and problems for this advancing technology to a section of short essays on the implications of our technological ability by practicing ethicists, lawyers, theologians, public policy workers, and scientists. Also included in this exploration is a panel discussion in which leading scientists, ethicists, and public policy workers give voice to their thoughts and concerns regarding our impending genetic technologies. Many of the world leaders in these fields: Leroy Hood, French Anderson, Mario Capecchi, Daniel Koshland, Michael Rose, Lee Silver, and James Watson, have contributed to this volume, providing the tools needed to debate the subject of germline engineering. If you have ever pondered the question: "Would I be willing to genetically alter my own child-to-be, given a safe, reliable technology, offering a tempting possibility?", this book will be an indispensable guide in that quest.
