We have our first C-V20 Big Y results, for kit 218881. FTDNA has more specifically classified him as C-F1628. FTDNA believes this is a subclade of C-V20. FTDNA also believes that F1628 is phylogenetically equivalent to V222, but it obviously is not, because this guy is V20+ F1628+ V222- .

He has 610 Novel Variants (by FTDNA's definition). Could that be a new "world's record" for the Big Y?

We still await Big Y results for two V222+ men, kits 171250 and N113953.

From paper:The Y-chromosome tree bursts into leaf: 13,000 high-confidence SNPs covering the majority of known clades
http://mbe.oxfordjournals.org/content/e ... 7.abstract
one Nepalese C-V20 sample nep-0172 share these SNPs with Japan C1a-M105 sample NA18974:

C18219322T CTS8809
G18929279C CTS9491
A21186044C Z4056
G22914979T CTS11043

according Ray Banks tree:
CTS8809 C1a1a P121 equivalents
CTS9491 C1a1a P121 equivalents
Z4056 C1a1a P121 equivalents
CTS11043 C1a

Does the C-V20 big Y results also have CTS8809,CTS9491,Z4056?

Kit 218881 is

CTS8809+
CTS9491+
Z4056+

CTS8809+

Thank you, it confirmed solid connection of C1 and C6. not someone suspect that CTS11043 is recurrent

He has now been placed as "new" on the YFull haplotree. Analysis of his BAM file is nowhere near complete, but these preliminary statistics have been released:

Private SNPs (all): 358
Best qual: 330 (92.18%) [282 (78.77%) - best; 48 (13.41%) - acceptable]
INDELs: 1 (0.28%)
Ambiguous qual: 21 (5.87%)
One read!: 0
Low qual: 6 (1.68%)

330 reliable (best- and acceptable-quality) SNPs, with each such SNP representing 140-150 years of patrilineage, equates to a TMRCA of 46-49 thousand years with the Japanese C1a1 (C-M8) clade.

Analysis of his BAM file is now complete. A couple dozen SNPs have been discarded, but the remaining number is still quite impressive:
Private SNPs (all): 331
Best qual: 312 (94.26%) [273 (82.48%) - best; 39 (11.78%) - acceptable]
INDELs: 0
Ambiguous qual: 18 (5.44%)
One read!: 0
Low qual: 1 (0.30%)

312 reliable private SNPs, at 140-150 years per SNP, equates to 44-47 thousand years since divergence from the Japanese C1a1.

A second C-V20 has just been submitted to YFull, and a third is waiting for his BAM file.

I have learned that three additional C-V20 men, with Western European surnames (Elliott, Coote, and Kisch), have Big Y results. I have sent them email suggesting that they submit their data to YFull, but I don't know whether any of them will do so.
