Distance between predicted CO and NCO breakpoints. Certain chromosomes were observed to have multiple COs (7C126 = 9, SC05 = 7) and NCOs (7C126 = 10, SC05 = 9). The distance between the beginning of the previous breakpoint window of an event and the start position of the consecutive breakpoint window of the next event was calculated. The distance between the different types of events were significantly different (P = 0.005). (A) NCOs were more commonly observed to occur within a shorter distance than COs. (B) When multiple COs occurred in a chromosome they were spaced > 200 kb apart.
