ABSTRACTAdvances in high throughput sequencing (HTS) enables application of single nucleotide polymorphism (SNP) panels for identification and mixture analysis. Large reference sets of characterized individuals with documented relationships, ethnicities, and admixture are not yet available for characterizing the impacts of different ethnicities, kinships, and admixture on identification and mixture search results for relatives and unrelated individuals. Models for the expected results are presented with comparison results on two in silico datasets spanning four ethnicities, extended kinship relationships, and also admixture between the four ethnicities.

AbstractHigh throughput sequencing (HTS) of single nucleotide polymorphisms (SNPs) provides additional applications for DNA forensics including identification, mixture analysis, kinship prediction, and biogeographic ancestry prediction. Public repositories of human genetic data are being rapidly generated and released, but the majorities of these samples are de-identified to protect privacy, and have little or no individual metadata such as appearance (photos), ethnicity, relatives, etc. A reference in silico dataset has been generated to enable development and testing of new DNA forensics algorithms. This dataset provides 11 million SNP profiles for individuals with defined ethnicities and family relationships spanning eight generations with admixture for a panel with 39,108 SNPs.
