Figure 4From: The prevalence of gene duplications and their ancient origin in Rhodobacter sphaeroides 2.4.1Location of gene duplications on chromosome I and II. These plots depict the distribution of the 234 duplicate pairs across CI and CII. The y-axis represents the level of divergence for a gene in a pair and the genes are color-coded to represent their COG function grouping. The plots reveal several clusters of gene duplications of similar COG function on CI and CII.Back to article page
