I’ve started proof reading my trees for haplogroup I sectors from Chromo2 raw data. I started with my own personal sector, Z138+/Z139+ It is now divided into 13 branches by the Chromo2 snps. See updated “Chromo2Z58”. The Z138 sector tree will be cleaned up; it developed like natural selection operates. I’ve got to figure out a more efficient proof reading method!
