In this paper, the authors describe an analysis of the previously published U.K. population allele frequencies from 370 Caucasian samples, 309 Afro-Caribbean samples, and 373 Indo-Pakistani samples, they also discuss the issues underlying the reporting of likelihood ratios (LRs) for genetically unrelated and related individuals from each of the three most common populations in the U.K.


The adoption of new 15 locus STR multiplex systems into UK forensic science would be facilitated by agreed guidelines for reporting the strength of DNA evidence using likelihood ratios. To facilitate such an agreement, the authors present an analysis of previously published UK allele frequencies for white Caucasian, Afro-Caribbean and Indo-Pakistani populations and investigate their effect on likelihood ratios for single donor profiles. They consider the implication of the five additional loci and suggest a procedure for reporting likelihood ratios for 15-plex STR profiles. (Publisher Abstract Provided)
