Question

which best describes mitochondrial dna (mtdna)? mitochondrial dna requires large amounts for testing. mitochondrial dna can be traced for generations. mitochondrial dna is inherited through the father. mitochondrial dna is the same as nuclear dna.

Explanation:

Mitochondrial DNA (mtDNA) is maternally - inherited and can be traced through many generations because it has a relatively slow mutation rate compared to nuclear DNA. It does not require large amounts for testing due to its high copy number in cells. It is not the same as nuclear DNA and is not inherited through the father.

Answer:

Mitochondrial DNA can be traced for generations.
