Abstract

Interpreting DNA mixtures of family members can be difficult. Probabilistic genotyping (PG) allows scientists to gain more information from their DNA data. The TrueAllele® Casework PG method separates out mixtures into individual genotypes and can then compare to references. These informative genotypes can accurately include or exclude family members. This talk describes a sexual assault case where a mixture sample was resolved to include one brother while excluding the other brother.
