Although they are all present, they are present in quantities so low that
makes it very difficult to believe that L21+ is a parent of M222+. Ancestral
to, possibly. Parental to, I doubt.
L21 is ancestral and parental to M222+ until another SNP comes along. The
fact that M222+ is so radically different from the rest of L21 might just
speak to the age of L21. I wonder if anyone out there has taken the L21+/M222+
samples and found a TMRCA estimate for the entire cluster? The latest
estimates for M222+ per David Wilson center on 1,500 to 2000 years BP. I'd be
willing to bet L21 is twice as old at a minimum for the haplotypes to have grown
so far apart.
The other SNPS downstream of L21 are basically meaningless at present.
