Abstract: Summary. The evaluation of nuclear DNA evidence for identification purposes is performed here taking account of the uncertainty about population parameters. Graphical models are used to detail the hypotheses being debated in a trial with the aim of obtaining a directed acyclic graph. Graphs also clarify the set of evidence that contributes to population inferences and they also describe the conditional independence structure of DNA evidence. Numerical illustrations are provided by re‐examining three case‐studies taken from the literature. Our calculations of the weight of evidence differ from those given by the authors of case‐studies in that they reveal more conservative values.
