    Biological material obtained from a crime scene is used to generate DNA-profile by typing short tandem repeat (STR) markers. However, if the STR-profile do not match the DNA profile of suspects or from a crime DNA database, the investigation can go towards typing markers that can estimate externally visible characteristics (EVCs). EVCs can function as a “biological witness” and thus aid a police ...
  • Analysis of 30 Y-chromosomal STR markers in the Norwegian population 

    Støtvig, Ingrid (Mastergradsoppgave; Master thesis, 2019-05-15)
    Autosomal STR-analysis is the standard method of DNA-typing in casework. However, there are forensic sample types that may contain a large fraction of female DNA and a minimal fraction of male DNA. The male fraction may not be successfully amplified using autosomal STR-analysis because it “drowns” in the female fraction. However, the analysis of male-specific YSTR markers may circumvent this obstacle. ...
