Figure 5From: Asymmetric and non-uniform evolution of recently duplicated human genesThe average dN for gene families and their average dS. Single-exon genes are shown as blue circles, genes with multiple-exons are represented by green triangles. Only genes with individual 0.005 ≤ dS ≤ 0.6 are shown. Linear regression trend lines are provided for single-exon and multiple-exon genes separately (regression coefficients not shown).Back to article page
