  1. The percentage of genes differentially expressed during the biological processes studied that have retained at least one ohnolog from a whole genome duplication event is given along with the total number of genes in the category ("Genes"). The last row in the table shows across the whole genome the percentage of genes that have retained ohnologs after each of the WGD events. WGD1, recent whole genome duplication; WGD2, intermediate whole genome duplication; WGD3, old whole genome duplication. Note that a given gene can have 0 or 1 ohnolog from the recent WGD, 0 to 2 ohnologs from the intermediate WGD and 0 to 4 ohnologs from the old WGD.
