I suppose there are different approaches to this issue. I am of the mindset that if a "new" SNP is available for purchase, it's best to have it tested by representatives of the various subgroups (even when it appears to be positive across the board). At the very least, this is useful to double-check results and to create a stronger foundation for future conclusions. With regards to L319, we will never know if it falls outside of the current STR-based divisions of Roots if people in that group do not test for it. Maybe these STR-based subgroups reflect convergence and not actually shared ancestry? We've had a similar case with P95, in which individuals were presumed to be P95+ based on their STR results but turned out to be P95- after testing. Maybe individuals who are presumed to be L319- are L319+? We'll never know if we simply ignore this SNP... As project administrator, I will always encourage testing of new SNP's by volunteers. The knowledge and certainty we gain are worth more than the $29 we'd save if we refused to test.

And L319 has been read from chromats to be - negative, ancestral for another in the same Roots clade as original L319+ So I think people in Roots ordering these snps is a questionable or "long-shot" venture.

He has me as basic M223*. Would these two fall into a category similar to L801? Cheers, Ian
