[[Syntenic dotplot]] of Vitis vinifera (grapevine) version 2 (x-axis) versus version 1 (y-axis).  Because grape, as with all eudicots, is derived from the [[eudicot paleohexaploidy]], each region of its genome is syntenic to two others.  However, the identical regions between these versions of the grapevine genome can be identified in this [[syntenic dotplot]] by their extensive syntenic signal.  This is seen by long, dense green lines in the dotplot.  Note the difference in these line such as reoriented contigs (inversion), where a syntenic line changes its slope and additional sequence in version 2, where a syntenic line has a gap in the x-axis.  Some pieces of version 1 chromosomes have moved to a new chromosome, as can be seen in chromosome 6.
