Distribution of COs on the genome comparing with Poisson model. (A) the distribution of all 91 COs suggests COs interference. Four different bin sizes are used, 100 kb for left upper graph, 200 kb for right upper one, 300 kb for left lower one, 400 kb for right lower one; (B) the distribution of small COs (max size < 1500 bp) is consistent with Poisson model; (C) the distribution of large COs (max size > 1500 bp) shows deviation from Poisson model, suggesting COs interference.
