Subject: [DNA] new world of SNPs in R1b

Hi again Lisa

previously identified.

Yes. Although not all the new SNPs are in this category this is the general
trend and what I was referring to.

> So, if you have a very close or exact match between two Rib haplotypes at,
say, 37 markers, a significant mismatch between them in the newer SNPs would
indicate, at the very least, no recent connection?

An EXACT match at 37 markers is rarely going to be an SNP mismatch, but
basically you are in the right direction here. More often it will be
"reasonably close" matches that can benefit from this cross check.
