Syntenic dotplot with Ks coloration of sorghum (x-axis) versus maize (y-axis). Genes are used for axis metrics. Results can be regenerated at: http://tinyurl.com/y9e778s. Red syntenic lines are from the maize-specific whole genome duplication event and are orthologous to sorghum. Purple are from the older pre-grass whole genome duplication event are are out-paralogs)
