Figure 1From: Weak preservation of local neutral substitution rates across mammalian genomesComparisons of substitution rates in orthologous ancestral repeat sequences from separate mammalian lineages. Z-score normalized rates for each repeat were calculated in the three lineages: primate, rodent and laurasiatheria. In each pair-wise comparison of lineages (the three graphs), rates are shown for every ancestral repeat having well-defined orthology among the four species. Pearson correlations r for each pair of lineages were found to be significant but with low predictive power (r2 < 5%) in each of the three comparisons.Back to article page
