Comparisons of codon bias, measured as, among each of the four Eichhornia genotypes, and the three selfing genotypes combined. is the mean of all positive ΔRSCU values for a given genotype. The results of two separate tests of significance are marked with A and B for the difference in mean between the outcrosser and the selfers combined (t = 1.99, P < 0.01). Bars indicate significant differences among individual genotypes using a Tukey-Kramer HSD (q* = 2.62, P < 0.01) with error bars indicating the standard error of each estimate.
