Distributions of KS values between paralogs or between orthologs. Th-α (Gg-α) refers to the distribution of KS values between paralogs in Tarenaya hassleriana (Gynandropsis gynandra) derived from the Th-α WGD event; the paralogs actually also include non-WGD duplicates. At-α refers to the distribution of KS values between paralogs in Arabidopsis thaliana derived from the At-α WGD event. “Gg versus Th” refers to the distribution of KS values between G. gynandra and T. hassleriana single copy genes. “At versus Th” refers to the distribution of KS values between A. thaliana and T. hassleriana single copy genes. Th-β (Gg-β) refers to the distribution of KS values between paralogs in T. hassleriana (G. gynandra) derived from the Th-β WGD event. The number (n) of gene pairs used: Gg-α: n = 3,454 paralogous pairs; Th-α: n = 6,787 paralogous pairs; Gg versus Th: n = 5,840 orthologous pairs of single-copy genes; At-α: n = 2,113 paralogous pairs; Gg-β: n = 224 paralogous pairs; Th-β: n = 295 paralogous pairs; At versus Th: n = 3,064 orthologous pairs of single copy genes.
