This volume brings together contributions exploring the mutual relationships between genetics, markets, societies, and identities in genetics and genomics. It draws upon the recent transdisciplinary debate on how socio-cultural factors influence understandings of ¿genetics2.0' and shows how individual and collective identities are challenged or reinforced by cultural meanings and practices of genetics. This book will become a standard reference for everyone seeking to make sense of the controversies and shifts in the field of genetics in the second decade of the twenty-first century.
