Philosophical scholarship on genetics and reproductive technologies typically follows the development of these scientific fields closely, providing critical analysis of the major assumptions and implications of their emerging claims, often in advance of their realization. This addendum reviews three discussions that have become particularly prominent in the literature since Ruth Macklin's original entry appeared in 1996: debates over the design and interpretation of human genetic variation research, the prospect of human reproductive cloning, and the potential limits of human genetic modification.

Human Genetic Variation Research

The principal outcome of the Human Genome Project was a set of research tools for human genetic variation research. With improved genomic maps and DNA sequencing technologies, geneticists have been able to launch a new generation of projects comparing human genomes to better understand our similarities, differences, and patterns of relationship at the molecular level. These...
