The so-called hypervariable regions (hv1 and hv2) of the human mitochondrial genome are sometimes used in forensic analysis. they are two noncoding regions of mtdna, each approximately 300 bp, that show more variation in different people than any other dna sequences. the dna within hv1 and hv2 appears to accumulate mutations at ten times the rate of dna sequences in the nuclear genome. check all statements that correctly describe situations where it would be advantageous to use mtdna (as opposed to nuclear dna) to identify individuals.
