Can someone please answer why some Haplogroup Ws matches Haplogroup Ns for both HVR1 and HVR2???
What haplogroup you belong in is defined by mutations outside of HVR1 and HVR2. Since 2003 FTDNA has used the more certain technique of testing for the defining mutation sequences on the mtdna outside of HVR1 and HVR2. So it is possible to be categorized as an N or W or L or whatever but have the same sequences in HVR1 and HVR2. The only difference between an N haplogroup motif and a W in HVR1 as per one minimum definition is the 16292T mutation in W. But 5.2% of N* individuals, also have the 16292T mutation. By logic of an HVR1 comparison only, they would be considered a W. And 7.4% of W’s lack the 16292T change. By an HVR1 comparison alone they would be considered N’s. But both have been classified using a different location outside of HVR1 and HVR2. Of the 203 combined N* and W haplogroup sequences on mitosearch, there are 2 cases where persons with N and W haplogroups have identical HVR1 and HVR2 sequences. One is HVR1: 16223T, 16519C / HVR2: 073G, 143A, 189G, 192C, 194T, 195C, 196
