Sec. 13. (a) As used in this section, "forensic DNA analysis" means an identification process in which the unique genetic code of an individual that is carried by the individual's deoxyribonucleic acid (DNA) is compared to genetic codes carried in DNA found in bodily substance samples obtained by a law enforcement agency in the exercise of the law enforcement agency's investigative function.
(b) In a criminal trial or hearing, the results of forensic DNA analysis are admissible in evidence without antecedent expert testimony that forensic DNA analysis provides a trustworthy and reliable method of identifying characteristics in an individual's genetic material.
