This article reports on a demonstration of how consideration of relatedness to the person of interest can be incorporated into a LR calculation and how the same calculation can be used for familial searches of complex mixtures.
Sophisticated methods of DNA profile interpretation have enabled scientists to calculate weights for genotype sets proposed to explain some observed data. Using standard formulae these weights can be incorporated into an LR calculation that considers two competing propositions. The current project provides a general formula that can be used in semi or fully automated methods of calculation and demonstrates their use by working through an example.
