| Most individuals who are Haplogroup I1 will be I1*, that is, root/ancestral
I1. Only a few SNPs usefully divide Hg I1, namely L22 and P109, which
appear most freqently in Scandinavia and define I1d and I1d1, repectively.
I1d-Norse is the most common Haplogroup I1 variety in Sweden
and Finland and is the second most common variety in Norway and Denmark.
Like I1-Norse, I1-Norse-D is most common in Sweden, Finland, Norway,
and Denmark, but the "D" variety leans toward Denmark (the value of 12
at DYS439 is what most distinguishes the D variety). I1d-ultraNorse
has its greatest frequency in Norway where it is the most common form of
I1. I1d-uN is the third most common form of I1 in Sweden and Denmark;
it is found only sparingly in southern and eastern Europe.
Among European haplotypes, DYS455=8 is virtually exclusive to I1
and YCAIIa,b=19,21 is universal in I1 (table cells highlighted in red).
In lieu of useful SNPs (the search for which is ongoing), varieties of
I1 have been defined by Nordtvedt based on STR haplotypes. Another
useful marker in this subclade is DYS511 (highlighted in royal blue
in the tables), which has a value of 10 in the Norse and ultraNorse
varieties and a value of
9 in the AngloSaxon varieties. Your
project administrator recommends all I1 individuals upgrade to 67 markers
to pick up the result for this marker. DYS462 is similarly
useful and can be ordered as a custom test from FTDNA. |
| Ken Nordtvedt is the guru researching Hg I subclades (see his Excel
spreadsheet). For a table showing modal haplotypes for his Hg
I varieties
in FamilyTreeDNA marker order, please also see my HTML
transcription of Nordtvedt's spreadsheet. Jim Cullen has developed
a predictor
for the varieties of Haplogroup I, and I have used it to make the determinations
below. In some cases, the predictor was not able to make a solid
determinaton, mostly in cases where not enough markers were tested.
I urge all participants to upgrade to at least 37 markers, preferably 67,
to get a solid prediction, and if you're predicted to be I1d, to be SNP
tested for L22. |
| I frankly have a problem with the way Nordtvedt has established
some of his varieties of I1. The issue is technical and has to do
with his clades not necessarily being monophyletic. This problem
rears its head with uN (ultraNorse) being both M253 and L22, which doesn't
jibe with uN being a clade. However, that need not really concern
us here. The important thing is that, as clusters (not clades),
they are useful. |
