This book is aimed at forensic scientists who are familiar with basic genetics but uncomfortable with statistics. The book begins with an introduction to basic probability theory and a demonstration of the Bayesian approach for interpreting forensic transfer evidence. Topics in basic statistics that are necessary for forensic scientists are covered, such as the theory underlying the estimation of allele proportions. Then the authors go on to consider the relevance of population genetics to forensic science, using population genetics in cases of disputed parentage and identification of human remains. Evett and Weir have concentrated on PCR nuclear DNA-based profiling systems, and have not included topics like mitochondrial DNA or measurement error. There are chapters on how to calculate match probabilities and how to explain such conclusions in a statement. Finally, the authors discuss the presentation of evidence in court. Complex mathematical ideas are separated from the main text, although a basic understanding of maths is assumed. There are also a number of exercises, with answers, to give the reader practice at the various techniques, and plenty of worked examples.
