While working on a client’s mitochondrial DNA report, I came across the worst case I’ve seen in a long time of mismatches being shown as matches at Ancestry.com. This has been a pervasive problem for a long time.
10 Point Question – If you match another person exactly on every location, HVR1&HVR2, must you have the exact same haplogroup?
Answer: Most of the time.
You didn’t think this was going to be easy did you?
Because Family Tree DNA is the only company to test to the full sequence level, their clients are going to have far more advanced, detailed and accurate haplogroup assignments than people who test at companies who only offer the HVR1+HVR2 regions.
Therefore, like in this case, we see a client whose haplogroup is H1. The “1” part of H1 is determined by location 3010A, a position found in the coding region that can only be read by full sequence…
