A new approach called Forensic DNA phenotyping (FDP) is an emerging technology which uses short tandem repeat (STR) to identify individuals. Next generation sequencing (NGS) is its only foundation. The practice of predicting an organism’s phenotype only from genetic data gathered through DNA sequencing or Genotyping is known as DNA phenotyping, another name for it is molecular photo fitting. Each individual is considered genetically unique, except monozygotic twins. This technique illustrates an individual’s externally visible characteristics (EVCs) from DNA which is obtained from biological samples. Eye, hair and skin colour can now be predicted reliably and accurately. Due to a lack of understanding of phenotypes, FDP has not yet been used on a regular basis in the field of forensic research. FDP will most likely have a bigger impact on criminal casework in the near future, notwithstanding recent advancements.
