Well, not a MAJOR change, but anyways pretty important: I received a message by Genographic, they wrote me they "refined" my genetic results. Well, I was a R-Z36; now, I'm a R-P37. The major clade is the same as before - R-U152, but the subclade appears significantly different. Geno shows me L2 as last step in my "Your deep ancestry - paternal haplogroup" section. L2 is a totally different clade than Z36!
Do you have any specifical info about my subclade? I can't find anything, anywhere. Did you experience haplogroup changes through time?
