Analysis of DNA multilocus profiles in a paternity case in which the child's profile may be partial

This report describes a simple approach to multilocus paternity analysis for cases where the child's sample may be inadequate leading to a partial profile. A specimen calculation is given. A previous paper described how the various band sharing configurations in the DNA multilocus profiles of a mother-child-putative father trio could be combined in a comprehensive mathematical analysis to give an overall Bayesian likelihood ratio. In that paper, it was assumed that all three members of the trio gave full DNA profiles. In some cases that assumption may not be valid but it is possible to extend the analysis to allow for partial profiles. This paper demonstrates how this may be done by considering the case where the child's profile may be partial for one reason or another. A specimen calculation is given.
