Comparison of calculated likelihood ratios (LR) based on the genotype data from STR loci D5S818 and CSF1PO, on a selection of cases.

Three different methods have been used, denoted M1, M2 and M3. M1: 50% recombination rate and LD not considered. M2: 30% recombination and LD not considered, M3: 30% recombination and LD taken into consideration. The column Comparison is the LR obtained using the software Familias with the standard Norwegian population database. WCS abbreviates Worst Case Scenario and attempts to simulate a case where the likelihood ratios should differ the most due to linkage disequilibrium. The columns to the right display three relevant quotients for each case; Note that the LR calculated using M2 and the quotient LRM1/LRM2 is only relevant in the non-paternity cases, since recombination alone will not effect the likelihoods for these cases.
