This book explains how DNA analysis works, from sample collection to interpretation of results, in language that is clear to professionals in the legal system, forensic science, and law enforcement.
Abstract
DNA analysis has its roots in classical genetics, biochemistry, and molecular biology; however, it has recently become a major player in criminal investigations and the identification of suspects. DNA findings are thus featured as evidence for the prosecution in criminal cases. This requires that judges, juries, and others with little or no training in the sciences that underlie DNA concepts make decisions based on DNA analysis. Couched in layman's language, this book emphasizes the advantages and limitations of various DNA techniques used in the analysis of forensic evidence. The authors discuss forensic DNA issues from both a scientific and a legal perspective. The chapters address key terminology used in the field, the scientific basis of DNA typing, statistical interpretations of DNA typing, and relevant court decisions and admissibility standards. The book features numerous graphics that illustrate DNA analysis, the clarification of general principles of complex DNA analysis techniques, and court evidentiary admissibility decisions. Chapter references, 15 appendixes of explanatory material, and a subject index
