Comparison of the distributions of Kas as a function of the evolution type of coding sequence length. Three Ka distributions are represented: Ka distribution of Buchnera genes that have the same length as their E. coli orthologues (blue), that are shorter than their E. coli orthologues (red) and are longer than their E. coli orthologues (black curve). The distributions shown in black and red are significantly different from the one shown in blue.
