Adapted from McClintok B. 1938. Ring chromosome undergoes three pathways, a even or no SCE pulled in the same direction results in normal division, b an number of SCE pulled in the opposite results in interlocked rings, c and odd number of SCE caused rings to merge into a mobius-like giant ring. d At any point of the process’ rings may break, causing the chromosome to be degraded
