Figure 3From: The nuclear OXPHOS genes in insecta: a common evolutionary origin, a common cis-regulatory motif, a common destiny for gene duplicatesDistribution of the inferred duplication (yellow boxes), intron gain (orange boxes) and intron loss (green boxes) events during evolution of the Drosophilidae and Culicidae species addressed in this work. The branch lengths are not proportional to age.Back to article page
