Subject: Dal Riata Modal Haplogroup - exact haplotype match.
Date: Sat, 17 Dec 2005 13:47:20 -0500


Hi Folks,

The following concerns two members of the Reddick / r320 surname project
where I'm the Co-Admin. These results relate to two distant cousins
(paper trails exist) whose results are predicted by FTDNA to be R1b.

Whit Athey's Predictor strongly places these two individuals within R1b
- as can be seen in the following results (provided by Whit) when their
two results are compared against the R1b modal haplogroup values. Whit
is appropriately cautious regarding these comparisons when comparing
these two results against the larger haplogroup of R1b. With scores of
76 and 80, they do appear to be R1b.

Would someone very knowledgable please comment on the likelihood of an
exact match to a 'sub-clade' modal haplogroup by one participant in a
study. This is the 'Scottish' Dal Riata Modal Haplogroup found within
R1b. Participant J. R. matches that modal group perfectly.

Is this all that common? Has anyone else seen such exact participant
matches to modal haplogroups in other studies? Is this merely numbers
and chance or is there something else to be learned here?

Rob Livingston provided me with the Dal Riata Modal Haplogroup values.
He and several other individuals come close to matching up with these
two members of the Reddick / r320 surname project whose ancestry does
appear to be Scottish.

19 17 38 39 12 12


J. F. R. differs from J. R. & the modal values on three fast-mutating
markers: DYS 576 - 19 / 18; DYS CDYa - 38 / 37; and DYS CDYb - 39 / 38,
respectively. This part of the results seems wholly normal and expected.
