Which best describes mitochondrial DNA (mtDNA)?
Mitochondrial DNA is the same as nuclear DNA.
Mitochondrial DNA is inherited through the father.
Mitochondrial DNA can be traced for generations.
Mitochondrial DNA requires large amounts for testing.
Mitochondrial DNA can be traced for generations.
The correct answer is: Mitochondrial DNA can be traced for generations.
Mitochondrial DNA (mtDNA) is a type of DNA found within the mitochondria of cells. Unlike nuclear DNA, which is inherited from both parents, mtDNA is inherited exclusively from the mother. This unique characteristic allows scientists to trace maternal lineage over multiple generations. Mitochondrial DNA analysis has been widely used in population genetics and ancestry studies.
