Respuesta :
DNA from fingerprints is useful when there is no body fluid left at a crime scene and when fingerprints are not sufficiently clear to provide reliable identification.
why is Identification from fingerprints is preferable?
Due to the larger database of fingerprints available for comparison, fingerprint identification is preferred to fingerprint identification over fingerprint identification via DNA; however, in cases where fingerprint ridges lack sufficient detail, fingerprint identification via DNA may still be the only option. As methods for extracting cells from a fingerprint and for DNA extraction become more effective, this method of identification will spread more widely.
