Question

how is mitochondrial dna (mtdna) typing used in forensic science? a suspects mtdna sample is matched to an unknown sample of nuclear dna that was found at a crime scene a suspects mtdna sample is matched to an unknown sample of mtdna that was found at a crime scene a suspects nuclear dna sample is matched to an unknown sample of nuclear dna that was found at a crime scene a suspects nuclear dna sample is matched to an unknown sample of mtdna that was found at a crime scene

Explanation:

In forensic science, mitochondrial DNA (mtDNA) typing involves matching a suspect's mtDNA sample to an unknown mtDNA sample found at a crime - scene. MtDNA is maternally inherited and useful when nuclear DNA is degraded or in low amounts. Nuclear DNA and mtDNA are different types of genetic material and should not be cross - matched in mtDNA typing.

Answer:

A suspect's mtDNA sample is matched to an unknown sample of mtDNA that was found at a crime scene
