Figure 4From: Weak preservation of local neutral substitution rates across mammalian genomesRepeat subclasses with high rate correlations. The repeats shown are those having correlation of ≥ 0.35 in at least one of the three lineage comparisons. Several of these (7SK, Charlie8, MER103, Charlie11, MER121, and MARNA), are likely to have been influenced by purifying selection, as they also exhibit lower than average substitution rates in all three lineages.Back to article page
