Dear Rootschat Members,
I am posting this message for Dr. Kenneth Nordtvedt who is not a member of this forum. He is one of the best-known researchers for Haplogroup I and would greatly appreciate seeing raw data files for anyone in Haplogroup I who has taken Chroma 2.0 from BritainsDNA. This test is proving to be of the greatest value in identifying SNPs in both I1 and I2, and the more files he has for analysis and comparison, the greater the value of the information provided by the test. So sharing will help you just as much as it will help Haplogroup I research.
If you have a file to share, please send me a private message and I will give you Dr. Nordtvedt's e-mail address.
Thank you.
Lindsey Britton

Message from Kenneth Nordtvedt:
"Chromo2 test contains over 14,000 Y snps. Comparing seven raw data files of
results from this chip, we have been able to see how fertile the chip has
been for haplogroup I; the locations we have been able examine have been
quite dense with new y snps. The maker of the Chromo2 chip had a goal to
produce a test particularly fruitful for folks from northern Europe and
British Isles, so they first searched for new snps accordingly and then
salted their discoveries into the Chromo2 chip.
You can see the new snps from Chromo2 appropriate to several sectors of
haplogroup I in my files:
"Tree for Isles L161"
"Chromo2I1work"
"Chromo2M223work"
found at website
http://knordtvedt.home.bresnan.net/ The L161 sector, the Z73 sector of I1, the Z138 sector of I1, the L126
Isles Scot of the M223 sector, and the Roots of the M223 sector are all
found to have many new snps. These results were obtained by comparing
seven Chromo2 raw data files I was able to receive from people. I am
grateful to those who shared their data.
To see how these many new Chromo2 snps further split our presently known
clades, we however need more Chromo2 raw data files to put into the
comparison spreadsheet.
If you have Chromo2 results please send me your raw
data file. Your contribution will be valuable
regardless of where in haplogroup I you reside, but especially so if you
fall in one of these sectors of the haplogroup previously mentioned.
I will publically present all findings in the formats I have already started
to set up in the named files above.
I was told that approximately 200 haplogroup I results were sent out
recently by BritainsDNA and their cohorts, ScotDNA, IrishDNA. Only seven
have been compared so far in the public arena. Imagine how much more we can
learn with more results brought into the comparisons. We can bring some
sectors of the haplogroup I tree right down into the historic era and close
to the genealogical era.
