Genomics ande the Future of Śledczy Science: Improving Accuracy andd Speed

Thee Role of Genomics in Forensic Science

Traditional methods have long relied on prinprint analysis, serologiy, and limited DNA testing - often using short tandem repeat (STR) markes. While these tools have provene effective, they face inherent limitations: fingerprints can be smudged or partial; DNA from STR analys may fail whene samples are degranded or contain a mixture of contribuils many of these omed besimples far more granulder tion information.

Moreover, genomic techniques allow exersic scientists to infer anciency, estimate physical appearance (distrigh DNA phenotyping), and evemon predict chronological age from specific epigenetic markes. These capabilities go far beyond simplified identification ande open thee door to investigative leads that were previously unimainteble. As a result, genomics is nomerely an increqumental improwiment - iment - ipresents a funtamental shift in hohows evidence is gad, expresented.
