Five of us have now tested at 23andme. In addition to autosomes, they test
for mtDNA and a thousand or more Y-SNPs. These are very old SNPs and are
not helpful for opening new routes to our ancestors. However, all five us
match almost exactly across those SNPs.
Note these points:
* The SNPs they've tested for each of us have a lot of variation. I
suspect that they're always fine-tuning by removing unnecessary tests and
adding new ones.
* "No-calls," indicated by a double dash, mean that the location was
tested for but a viable reading didn't occur.
* "D" means deletion, "I" means insertion.
* These SNPs have no official names (like our L448 SNP). Those that start
with "rs" are standardized reference numbers. Those that start with "i"
are reference numbers internal to 23andme.

My take? Of course, this a very small sample, but there's no real
consistency between Don and his dad, and between Jack and his uncle. It
may well be that 23andme has determined they're too volatile to be of use,
which might explain why neither Jack nor I were tested for rs9786488.
Still, we match on all the others that were mutually tested for and for
which there were viable calls. I'm thinking of creating an interface
(maybe I'll call it "the Cooley R-L448 DNA Project!") so that other
R1a-L448s can run comparisons and receive results like those above. We
might learn something. For example, do all L448s have that out-of-place
Chinese SNP, P198?
