L48 is the largest sub-group below R1b-U106.
With this DNA test we start with 5 key SNPs:
L47
Z9
Z2
Z8
Z326
and then we work down the branches iteratively until we have found your position on the given tree.
The test is completed when the unique phylogenetic position on the
tree has been determined.
