Final answer:

Mitochondrial DNA (mtDNA) is a unique genetic material passed down unchanged maternally, useful in genetic studies. Samples like a single tooth at a crime scene contain mtDNA but lack nuclear DNA.


Explanation:

Mitochondrial DNA (mtDNA) is a type of DNA found in the mitochondria that is passed down unchanged from the female genetic contributor to the child. It lacks recombination, making it a useful tool in genetic studies. Samples such as a single tooth found at a crime scene would likely contain mitochondrial DNA but lack nuclear DNA, providing valuable genetic information for analysis.
