  • FP and PP are the numbers of silent changes from an unpreferred codon to a preferred codon that are fixed and polymorphic, respectively. FU and PU are the numbers of changes from a preferred codon to an unpreferred codon that are fixed and polymorphic, respectively. FNC and PNC are the numbers of changes that did not change the category of codon (e.g., changes from preferred to preferred or from unpreferred to unpreferred) that are fixed and polymorphic, respectively. P values were determined using 105 replicates of a Monte Carlo procedure. Note that in no case was there significant heterogeneity among the classes of codon fixations.
