Skyline reconstructions of the demographics of all ten protein-coding genes. The effective population size (Ne) scaled to generation time (τ) is plotted against absolute time, expressed in years before 2009. (A): for the three genes with decreasing Ne × τ are represented by filled symbols. (B): for the seven genes with the recent increase in Ne × τ.
