Effect of Pr(D) on LR. S is ab, E is a. The likelihood ratio LR = Pr(E\Hp)/Pr(E\Hd) is plotted as a function of Pr(D) ∈ [0,1]. Locus D18S51 frequencies are used as an example, where allele a corresponds to D18S51 allele 13 (frequency: 0.135). Using the 2p rule: LR = 1/(2pa) = 1/(2 × 0.135) = 3.8 (dashed line).
