Functional analysis of asymmetric changes in the rates of evolution after WGD. a Fraction of orthogroups for which the alternative R4 hypothesis (ω_a1,a2 ≠ ω_b1,b2) is accepted; plot shows data for all orthogroups (black bar) and different functional annotations (gray bars). Functional annotations depleted in asymmetric-rate orthogroups are shown (***p < 0.001, χ ² test). b Histogram shows the distribution of protein abundances of the low-rate paralog relative to its high-rate paralog. c Scatter plot shows absolute protein abundances of the high-rate paralog compared to its low-rate paralog. Color scale indicates the absolute difference between the Codon Adaptation Indexes of the paralogs (CAI-diff). Black circles indicate all genes encoding for metabolic enzymes
