Subject: [DNA] Continental I1b2a (old I1c)

Someone asked me what we knew about separation of the two types of Continental I1b2a (old I1c), so I thought I'd send my answer to the list since it's a fairly big clade. There are actually three kinds of continental I1b2a, with the third having its own SNP, P78+, but which is much smaller in western Europe at least (P78+ has an Eastern Europe flavor to it, or perhaps presence among Jewish males).

Continental I1b2a 1 vs 2 seems to separate best using H4 --- 9 versus 10 (FTDNA convention) The former had 83 haplotypes in SMGF, and the latter 153.

The former looks much more concentrated in Frisia --- from Denmark to Netherlands. The latter is a bit stronger in Scandinavia. Both show over representation on the continent as compared to the British Isles, although the latter does somewhat better in the British Isles than the former.

I have found many varieties within haplogroup I. Separating I1b2a-Continental 1 vs 2 is the hardest nut to crack

A list friend has developed an innovative way to produce phylogenetic trees. He shared with me his tree for the entire haplogroup I. All my robust varieties separated very well in his tree outside of I1a except I1b2a-Continental 1 & 2 which just sort of separate.

The above conclusions come from SMGF data.
