| ===Definition===
| |
| A genomic inversion is when a region of a genome or chromosome gets flipped in place. These usually happen at genomic regions with nearly identical sequence, implying a mechanism similar to non-homologous recombination.

| | |
| ===Bacteria===
| |
| In bacterial genomes, inversion often occur at transposon or ribosomal gene sequences, and happen symmetrically around the [[origin of replication]]. The latter causes a characteristic pattern in [[syntenic dotplots]] called an [[x alignment]].
