It depends on how recently the haplogroups were formed. For example, the
haplotype 14-12-24-11-13-13-13-29 is found in R1b, R1b6, and R1b8 in a small
dataset on Garvey's site. R1b6 and R1b8 are "recent" offshoots of R1b. That
haplotype wasn't found in offshoots of deeper branches, e.g. J or E3 in this
dataset. The haplotypes for those groups are quite different.

Probably, as in the example above, which is using the nomenclature from the
2002 phylogenetic tree. (The R1b section has been renumbered for 2003)
