This is a completely revised edition of a comprehensive and popular introduction to the fast moving area of Forensic Genetics. The text begins with key concepts needed to fully appreciate the subject and moves on to examine the latest developments in the field. Now illustrated in full colour throughout, this accessible textbook includes numerous references to relevant casework. With information on the full process of DNA evidence from collection at the scene of acrime to presentation in a legal context this book provides a complete overview of the field INDICE: Foreword.
