Nelda, if you won't mind, I will make a few corrections here.

It's HVR intead of HRV. HVR stands for "hypervariable control region".

The 15,000-17,000 number refers to the number of base pairs (not
markers) in the entire mtDNA. There are fewer than 1200 base pairs in
just the HVR1 and HVR2 regions.
