Subject: [DNA] R-L21 possible areas of origin
Date: Sat, 9 Jan 2010 20:15:30 -0800


Dear All,
It has been some time since I last looked at the R-L21 data in
regards to possible areas of origin based on intraclade TMRCA estimates.
See

27 and
http://archiver.rootsweb.ancestry.com/th/read/GENEALOGY-DNA/2009-07/12486746
33 for background. There are now about twice as many R-L21 haplotypes
available as compared to 8 months ago. I thus decided to analyze the
currently available 67-marker haplotypes from the FTDNA R-21 project at
http://www.familytreedna.com/public/R-L21/default.aspx?section=yresults to
see if the current data supports any particular theory in regards to the
area of origin of R-L21. The current data shows that R-L21 has the highest
variance in England. Below are intraclade TMRCA estimates using various
marker sets for groups of haplotypes from various geographical regions. The
TMRCA estimates for samples from Great Britain and Ireland are slightly
older than the TMRCA estimates for samples from Continental Europe.
Sincerely,
Tim Janzen
