If DNA from an evidence sample and DNA from a suspect or victimshare a profile that has a low frequency in the population, thissuggests that the two DNA samples came from the same person; thelower the frequency, the stronger the evidence. But the possibilityremains that the match is only apparent—that an error has occurredand the true profile of one of the sources differs from thatreported by the laboratory. Please discuss the ways that laboratoryerrors, particularly errors that might falsely incriminate asuspect, can arise, how their occurrence might be minimized, andhow to take into account the fact that the error rate can never bereduced to zero.
Please discuss the quality assurance and control.
