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 human nuclear DNA (as opposed to mtDNA) to identify individuals.
a. Very little DNA is recovered from the scene of a crime.
b. You want to determine which of two brothers is the father of a child.
c. You want to determine if two individuals are identical or fraternal twins.
d. You want to determine if the woman you've been told all your life is your mother is really your grandmother.
e. You want to determine if two people are first cousins.
