Abstract

The widespread application of DNA profiling has brought to some prominence the issue of close relatives sharing body fluid types. In a particular crime case it may be suggested that a close relative of the suspect was the person responsible. This paper explains how an assessment may be made in the context of single locus profiling and where the suggestion is that a full sibling is involved. A formula is established for the likelihood ratio which is then worked out in detail for the particular case where the suspect profile has two distinct bands. Generalization to other types of case is briefly explained and there is a short discussion of the impact of the evidence in the context of a trial. For all parties, justice will best be done if the scientist has ample notice, before the trial, of relationship issues such as this one.
