Table 1. Numbers of amino acid sites and genes with convergent and non-convergent replacements in reference branch comparisons.

Comparisons were made between pairs of C₄:C₄, C₃:C₃ and C₃:C₄ branches. Numbers of replacements unique to a given category (*), and the corresponding ratios Con:NC (Ratio). Differences between the C₃:C₃ and C₄:C₄ categories are not statistically significant (P ≥ 0.05, Boschloos test).

	C 4 :C 4			C 3 :C 4			C 3 :C 3
