Expression profile of Argonaute 2. Plots show the difference in expression between female (red) and male (blue) flies, based on public RNAseq data, normalized to rpL32 and plotted on a natural log scale. The significance of differences between the sexes was assessed using a linear model fitted with MCMCglmm and is denoted by asterisks: * 0.001 < pMCMC < 0.05; ** pMCMC <= 0.001). Sample size (n) represents the number of RNAseq datasets used (combined across tissues). Ago2d is the ancestral copy in Dpse and Dmir, Ago2a is the ancestral copy in D. obscura and Ago2a is recently duplicated in Dpse become Ago2a1 (Ago2a) and Ago2a3
