Provides the theoretical underpinnings for interpreting matching DNA profiles and the means to express evidentiary strength in courts of law. A sampling of topics: probability theory, transfer evidence, basic statistics, population and statistical genetics, parentage testing, mixtures, calculating match probabilities, and presenting evidence in court with particular reference to recent cases in the UK. Since the focus is on the current generation of polymerase chain reaction nuclear DNAbased profiling systems, there is no discussion of match/binning or of mitochondrial DNA statistics. The anticipated audience is forensic science and legal professionals who have some understanding of the current uses of DNA profiling. Annotation c. by Book News, Inc., Portland, Or.
