Subject: [DNA] Identifying R1b clusters using Fluxus Network
Date: Thu, 7 Jun 2007 13:41:41 -0400


The FTDNA R1b project has 415 entries which have SNP-confirmed
haplogroup assignments and 67 STR markers tested. Taking this set and
feeding the data into Fluxus Engineering's Network phylogenetic
software, yields the following phylogenetic diagram, after much
massaging to try to isolate recognizable clusters:

The diagram show I think the usefulness of phylogenetic software in
identifying clusters. Not only is the R1b1c7 cluster clearly separable
(based on its known recognizable STR pattern), but several other
clusters are evident. Taking the three largest ones, circled in green,
it turns out that one corresponds to Irish type III and a second to
the North Sea modal.

The third cluster, on the right of the figure, is the infamous
DYS425=null. Besides having DYS425=null for all 7 members, DYS511=9
(for 5 of the 7 members anyway), whereas only 3% of R1b generally has
DYS11=9.

There are some smaller clusters of 4 and 5 members that may or may not
turn out to be representative of known clusters.
