[[[[Then what you and others go on to say, it seems a nucleotide site must
have already been found to be a ysnp within the modern man tree to have been
included in the eventual 2042 in the 23andMe test. In other words, there
are no just randomly selected nucleotide sites. So I don't understand why
they all did not appear in YCC or someone's tree. What subset made the YCC
acceptance criteria for inclusion in their published tree? To be specific; I
recently found three ysnps from 23andMe and Decode comparisons which occured
on the terminal branch segment leading to an I2b* dna sample. Why did not
those three appear in someone's journal paper? How did they get from
NOWHERE to being on the expanded chip? I still don't understand where they
all came from and whether they are exhaustive in some sense? ]]]]]]
