Figure 6

Plot of the average distance between all paracopies in a family. Each data point represents the average amino acid distance D_af between all paracopies of a peptide family for each amino acid position throughout the species as outlined in (a). (b-d) The mean ± standard deviation of the data (b) for single copy peptides (c) and multiple copy peptide families (d). Paracopy number is color-coded in (d): black, 2; blue, 3; red, 4; green, 5; purple, 6; and brown, 10-17. The asterisks indicate a significant difference between multiple and single copy peptides.
