Identification of duplicate genes and their relationship with duplication age. a Schematic diagram of duplication types in the maize genome relative to sorghum. Duplications were classified into three major patterns: whole genome duplication (WGD), tandem duplication and inserted duplication (located in non-syntenic positions). Boxes represent genes and the grey area shows the homologous relationship of genes between maize subgenomes or between species. “Other region” refers to a non-syntenic genomic location. b The number of duplicate gene pairs in different duplication types. c The synonomous mutation (dS) distribution of duplicate genes across different duplication types. sd(WGD) shows the standard deviation of dS of WGD pairs
