G-Z726

This is the home page for the men predicted or confirmed Z726 and negative for
its subgroup.   Z726 was first identified in samples from the 1000 Genomes 
Project, but it was not until 2013 that we were able to obtain a separate test for it.

The above diagram shows Z726's position in the G tree.  It is the youngest of a
series of mutations, each one covering fewer persons as the tree branched.
All Z726 men have all the mutations shown above it in the tree.

A separate page exists for each of these mutations and the persons covered by them.
See tabs on left.   The G-L497, G-L140, G-P287 and G-M201 pages have significant 
additional information.  

L43 is the sister subgroup of Z726.  Because each shares some different ancestors
in more recent times, each can belong to one subgroup but not to the other.

Z726 has two SNP-defined subgroups, CTS4803 and Z16775.   It is also has three subgroups defined
by sharing a marker value oddity.  These are the subgroups consisting of men who have 
the odd value of 15 at marker DYS388 and the one with 7 at DYS391 and one with
10 at marker DYS459b.  
When men from these subgroups have full Y-DNA sequencing, there will be more reliable 
SNPs identified to replace the shared marker value mutations, and these subgroups will 
then have pages of their own here.  It is currently undetermined the status of DYS388=15 and 
and DYS391=7 and DYS459b=10 men for CTS4803.  If they turn out part of that subgroup, 
they will be moved to the CTS4803 page.

Age of Z726

At this writing, there is just one man Z726+ and negative for its subgroup.  So no
conclusions can be made about men in such a situation.  Based on available information,
the common ancestor of all Z726 men seems to have lived no more than 2500 yrs ago.
Additional samples may cause this to expand back in time.  Presently also several Z726
men are undergoing full sequencing of Y-DNA.  We also have one such man with 
full sequencing from the Personal Genomes Project already available.  And there are
two Z726+ men from the 1000 Genomes Project with partial sequencing.

Geographical Distribution of Z726

Because only one man so far is Z726+ and also negative for the subgroup nothing can be said
of the geographical coverage of men with such findings.

The DYS388=15 subgroup seems to be confined to men with British Isles ancestry. 
The DYS391=7 subgroup is 100% Spanish.  
The DYS459b=10 subgroup is heavily English with one Swedish member.

Origins of Z726

Again, at this writing, having but a lone man who is Z726+, CTS4803- makes it impossible
to draw conclusions.  And it is not known how the DYS388=15 and DYS425=15 and
DYS459b=10 subgroups developed.
