Standard errors are in parenthesis. Different letters for each parameter within each length class (a versus b) indicate a statistically significant difference using randomization tests (P < 0.05). As unbiased long CDS had N = 3, the parameter values were included for completeness, but were not used in randomization tests. dN, nonsynonymous substitution rate; dS, synonymous substitution rate; Fop, frequency of optimal codons.
The unbiased short CDS exhibit a statistically significant difference from testis- and ovary-biased CDS (short and long), P < 0.05.
