Explanation:
I got it right lol and have a good day <3
Option B A suspect’s mtDNA sample is matched to an unknown sample of mtDNA that was found at a crime scene is correct.
What is Mitochondrial DNA (mtDNA) typing?Mitochondrial DNA (mtDNA) typing is used in forensic science to analyze DNA evidence in cases where the DNA material is degraded or present in small amounts, such as in hair shafts, bones, and teeth.
mtDNA typing is also useful in cases where a person's nuclear DNA (which is unique to each individual) is not available or is contaminated with DNA from multiple sources.
mtDNA is inherited maternally and is present in multiple copies in each cell, making it more abundant and resistant to degradation than nuclear DNA.
Forensic scientists can compare the mtDNA profile of a suspect with mtDNA evidence found at a crime scene to determine whether the suspect's DNA could have contributed to the evidence.
Since mtDNA is not unique to each individual and is shared among maternal relatives, mtDNA evidence alone cannot definitively identify a suspect, but it can help exclude individuals who do not share a common mtDNA profile with the evidence.
Hence option B is correct.
