Pairwise alignments of sequences containing structural variation (vertical axis) against a reference sequence (horizontal axis). Diagonal lines indicate alignment matches; horizontal gaps correspond to deletions with respect to the reference; and vertical gaps correspond to insertions with respect to the reference. a Simple deletion, b simple insertion, c simple inversion, d dispersed duplication, e tandem duplication, f loss of repetitive sequence, g gain of repetitive sequence, h deletion with breakpoints in repetitive sequence. Note that in the last three examples there are multiple pairs of breakpoint coordinates that would result in the same observed rearrangement
