yDNA Project Report 5 November 2007: Initial Analysis Summary Return to Analysis Report Index prior report next report
Initial Analysis -- Summary:   The following graph visually summarizes what we know so far. Of the 21 profiles in the project as of Novemer 2007, 6 tested at the 12 marker level which is only used for high-level migration analysis.   They are included here in their own "12s" group.  The other 15 profiles tested at 25, 37 or 64 marker levels.  The 25 marker level is good for initial pattern analysis, as demonstrated below, although the 37 marker level is what we should encourage all participants to submit.  The 37 marker level is just better for genealogical analysis. The 25 marker pattern analysis shows 6 to 8 Clan Branch patterns. 6 are shown here.  The other 2 are noted in-line to the images below. The closer the profile Id's are to each other the more likely there is a "genealogically" significant relationship. That term means that two individuals may have a comon ancestor within the last 1,200 years. Within several of the Clan Branches we have examples of those potential common recent ancestors.  However most of our Clan Branches are at the far end of that scale from the Clan Modal profile. We are an historically ancient and varied Clan with many facets.
The spreadsheet summary below groups each profile with its tentatively assigned Branch-Modal value. The leftmost column is the branch group indicator. The rightmost two columns show the distance when compared to the Clan_modal profile and that branch group's modal profile. Mind you there are still too few participants for this to be anything but tentative. Also listed is each branch group's modal profile and shown, to the right of each, how distant that group's modal profile is from the clan modal profile.
Branch Group Summaries:    The following 7 sections pare down the results to each Branch Group to make it easier to review that group:
Group "A" has two members (68777 & 96288) that match at 25 makers;  Profile 89776 is outer edge but listed here for analysis.
Group "B" is some distance from the rest of the Clan;  The two members also differ from each other in many aspects but do have two common couplets (8/9 at 459a/459b; and 13/13 at 464a/464b) so listed  together here for analysis.
Group "C" has a common couplet 18/30 at 448/449.
Group "D" shows a strong group pattern but curiously most of the individual profiles are further from each other than from their common branch modal profile.
Profile 84534 is the sole current member of this Group "E" at the 25 marker level.  However, at the 12 marker level,  profile 13771 (see below) shares a triplet 13/13/28 at 388/439/389-2
Profile 96471 is the sole current member of this Group "F"
Group "12s" collects all the profiles that only have 12 markers since we cannot directly compare their profiles with those having 25 or more markers. But they do belong in the analysis and we are delighted to have them participate at this level.
