Scholarcy highlights

  • Forensic DNA phenotyping encompasses a set of technologies geared towards inferring externally visible characteristics from DNA traces found at crime scenes
  • The faces in the top row display the average effects of ancestry on facial shape, the heat maps in the bottom row each show different things
  • This typically depends on which analyses were requested by the prosecutor, the amount of DNA available, and analyses previously performed on the trace
  • HVR refers to Hyper Variable Region, one part of the mitochondrial DNA genome
  • These translations became clear through an interview the first author conducted with Dutch police officers on 05/10/2017
  • This technology was provided to Parabon by a US lab that works on predicting facial morphology
  • We thank all the members of the laboratories for their openness and patience in introducing us to phenotyping technologies
