Tandem duplication hypothesis. A hypothetical scenario of evolution from an ancestral sequence to Zea mays ssp. parviglumis through tandem duplication, followed by deletions and inversions. Duplicated synteny anchors are written in bold face and the synteny anchors involved into the tandem duplication event are depicted in a frame box. Lost synteny anchors are stricked and inversion is underlined.
