Question for the R1b gurus.
I do not understand how I could have tested Z49+ if I already tested L20- and L196-. On the ISOGG tree Z49 falls below both L196 and L20 and I tested negative for both of those. Is there a mistake in the tree or is everyone just trying to figure where Z49 should be placed?
