I’m curious what the Chromo2 S1990 versus S2001 division in the YSC00261+ AS1/AS8 clades will turn out to correspond to in the large haplotype population? Maybe we will know with a few BigY results from this sector? See “Chromo2Z58”. Kenneth Nordtvedt Haplogroup I Clade Modalities and Trees at: http://knordtvedt.home.bresnan.net
