Answer: having untested DNA samples
Step-by-step explanation:
Having untested DNA sample can be considered as the negative consequences of the using the DNA technology. The results of the DNA technology are accepted worldwide in the criminal justice system, in paternity and maternity disputes, and in identification of the missing person. Keeping the untested DNA sample can make the sample useless. Also making report without applying the DNA technology and only using the presumptive test can make the results unconfirmatory.
