Correlation between absolute synonymous and nonsynonymous rates. Absolute rates of nonsynonymous (RN) and synonymous (RS) substitution from Table 4 were log-transformed and then plotted for each terminal branch. Log(RS) values are on the horizontal axis and Log(RN) values are on the vertical axis. The solid black line is a linear regression of the data. The broken line signifies an RN to RS ratio of 1.
