Figure 4From: Evolutionary constraints and expression analysis of gene duplications in Rhodobacter sphaeroides 2.4.1Average ω values of in-paralog gene-pairs contained within CI, within CII, within plasmids, and between CI and CII. The distribution of the average values of ω suggests that inparalog gene-pairs, which are located on different chromosomes, experience different selection pressures.Back to article page
