A Comparison of Synonymous Codon Usage Bias Patterns in DNA and RNA Virus Genomes: Quantifying the Relative Importance of Mutational Pressure and Natural Selection
Figure 6
Variation partitioning of codon usage patterns attributed to mutation and selection for DNA (a) and RNA (b) viruses. The meaning of each part of the variation is interpreted as follows, : proportion of variation explained by mutation; : proportion of variation explained by selection; : proportion of variation explained by the interaction of selection and mutation; : proportion of unexplained variation.
