This volume applies the principles of Christian ethics in examining recent significant developments in the science of genetics. Derived from a modified version of virtue ethics, the book draws particularly on a classical understanding of the virtues, especially prudence or practical wisdom and justice. It considers ethical issues arising out of specific practices in human genetics, including genetic screening, gene patenting, gene therapy and genetic counselling as well as feminist concerns. The book demonstrates that a theological voice is highly relevant to contested ethical debates about genetics.
