Figure 1

Whisker box plots detailing the variation in K _a and K _s for in-paralogs (I), out-paralogs (O), and all paralogs (I + O). The distributions of K _a (panel A), and K _s (panel B) are shown as box plots with the box representing the interquartile range (25%–75%), the thick solid horizontal line indicating the median, the dot indicating the mean, and the circles indicating the outliers. The plots illustrate and confirm that in-paralogs and out-paralogs possess different distributions of K _a and K _s values.
