The WHG component in the EHG seems to be unsampled. I say, if we do find the source of the WHG component.
The 1990s called, they said they want their low quality admix tools back.You will not find, because WHG is a hybrid of CM and EHG.
There is IJ in WHG. One of those IJs if I recall correctly had an upstream clade closer to J than to I.Have we found J amongst WHG? I believe the hgs found have been I, C, and R-V88.
