Since there are many software implementations that address a range of inference problems spanning identification and relationship testing, this article proposes a flexible likelihood ratio framework that caters to inference problems in forensic genetics.


Forensic DNA profiling is used in various circumstances to evaluate support for two competing propositions with the assignment of a likelihood ratio. The framework proposed in this article enables the investigation of the degree of support for the contribution of multiple persons to multiple samples allowing for persons to be related according to a pedigree, including inbred relationships. The article explains how many routine and more complex problems can be treated within this framework. (publisher abstract modified)
