Many members of the cluster have ordered tests of their SNP markers, either as Deep Clade-R, or as individual SNPs. The results show derived or positive (+ve) for S116 or P312 and S145 or L21. In November 2009, a new SNP was found in the "Walk The Y" project at FTDNA. This SNP, L226 has shown to be positive for all Irish Type III who have tested and negative for members of all other R1b clusters. This, (prior to the Big-Y testing, 2014) is the last +ve SNP and so we are now R-L226 (or R1b1a2a1a2c1f2a) and is defining for our haplogroup.
EthnoAncestry, Britain's/Scotland's DNA, advise S168 is equivalent to FTDNA's L226.
If you suspect that you are Irish Type III, just test L226 from the Advanced Markers page at FTDNA. There is no need to do a Deep Clade test or Geno 2.0 which is considerably more expensive that just testing the one marker. L226/S168.
I encourage ALL Irish Type III members to test this SNP and to join the R-L226 project at FTDNA.
PLEASE - When requesting to join the R-L226 project, include your Kit Number and say if you have ordered the L226 SNP - Thank you.
How do I Order L226?
This marker can be ordered from your FTDNA Home Page.
Go to your Home Page / yDNA / Haplotree & SNPs / and scroll down the chart to
[R-L226 Add]in Blue half way down the page, or using Ctrl-F, search for L226. Click on the 'Add' button. Now click on the 'Continue Order' button to process your order.
If you order this marker, please also join the R-L226 project at FTDNA. I will place you in the 'Pending' group until your results come in.
Irish Type III men who have tested L226+ are shown here R-L226 Project Results.
All that test positive for L226 are invited to join the R-L226 Project at FTDNA.
The R-Tree at ISOGG shows how the SNP s separate the various branches of the R Clade.
Next Generation Sequencing SNP Testing
From 2014, a new SNP test has been released by FTDNA called 'Big-Y'. Two new SNPs are being used to check for branching below L226, FGC5628 and DC1
More detail on this NGS type test can be found on the Big-Y Testing page.
