Figure 5
Similarity in sequence divergence between regions of shuffled genes. The amino-acid divergences (Ka) of recombined domains to their respective parental counterparts are correlated. One outlying observation (Ka1 = 3.26 and Ka2 = 0.36) is not shown in this plot but was included in the calculation of correlation coefficients. Excluding this observation increases the Pearson correlation coefficient to 0.61 and leaves the Spearman correlation coefficient unchanged (P < 0.0001 for both).
