Beyond Reasonable Doubt: Evolution from DNA Sequences
Figure 4
Protein length versus proportion of pairwise alignment scores higher than the ancestral score, for 4 datasets.
Because of the possibility of slightly different gene lengths just one of the two datasets is used for illustration. As expected, longer proteins show convergence more strongly. Chloroplast results (4A and 4B) are for 51 chloroplast genes for divergences of monocots and for angiosperms (flowering plants). There are 7 nuclear proteins for 4C and 12 for the mitochondrial data in 4D.
