Using the many Geno2 raw data results I isolated the snps which appear phyloequivalent to M253 right now. There are about 50 of them. Some are also seen on the Chromo2 list of same. The Z131+ and DF29- Z131- persons with Geno2 results show derived for all of these. If that ancestral line from DF29 back to the beginning of haplogroup I is 18,000 years long, 50 snps means on average about one every 360 years. That has implications about how far back can the Z131 branching point be and about our chances of using AS1212 or AS121210 person to split one of these 50 snps off from equivalence. How many more such snps phyloequivalent to M253 will be found with BigY, I don’t know, but it does not seem like it will be a very large number unless we don’t understand the snp mutation rate.

Actually, if mutation rate for average snp in the BigY is 2/100 million, then BigY would produce a snp about every 150 years on average along a tree branch line. So the number of additional snps from BigY would still be very impressive --- another 50 to 100 phyloequivalent snps. We should know in a month or so I hope.
