A series of nested or overlapping inversions produce DS patterns at ends of the rearranged segments. Yellow lines between steps indicate the chromosomal segments that are inverted between rearrangement steps. Note that the complexity of resulting DS patterns is enhanced if genes highlighted in pink or blue result from previous translocations between chromosomes, or if the inversion process is combined with fissions, fusions and translocations. Moreover, the timing of rearrangement and the lineage in which the rearrangement occurs will further delimit the DS patterns produced. Ultimately, DS patterns arise from a comparative exercise that is set by the user.
