Figure 2.

Scatterplots of the three molecular clock parameter estimates obtained for each partition, calculated using the uncorrelated lognormal (UCLN) relaxed clock model. Colouring is the same as that in Figure 1: among host subtype 1a data set (green squares), among host subtype 1b data set (blue triangles) and within-host data set (red circles). (a) Plot of mean evolutionary rate versus the coefficient of variation. (b) Plot of mean evolutionary rate versus the codon rate ration. (c) Plot of the coefficient of variation versus the codon rate ration. See main text for full description of each parameter. For each plot, the correlation coefficient (r) and statistical significance (p) of the relationships are given.
