Sequenced Breakpoints of Crossover Suppressor/Inversion qC1

We used whole-genome sequencing (WGS) data from a number of balanced lethal strains in Caenorhabditis elegans to show that the crossover suppressor qC1 is an inversion. The rearrangement is complex, with a large primary inversion that contains several other smaller inverted regions. The graphical representation below depicts these various qC1 rearrangements for ease of conceptualization. It is the simplest chromosomal structure compatible with the data currently available, but even then it is worth noting that the complexity of the qC1 chromosome can make the graphical reconstruction difficult to understand, and it may seem a bit like relativity theory or artwork from M.C.
