The theory about J2b(xJ2b2):
1) this subclade haven't separate branch because somehow their haplotypes can mutate (like mimicry) in such a way that it not differs from J2b2 on the Tree
2) it was a case of mistaken identity M241- by lab (like N6065 (were M241- and now M241+)
3) changes are in process on M102 -> M241 -> M102 in the other words M241- it's reverse deletion (!)
