Fig. 2From: Identifying branch-specific positive selection throughout the regulatory genome using an appropriate proxy neutralFinding a neutral proxy. a. Distribution of the number of local reference alignments around each DNA element within three different distances: 10 kb, 40 kb and 100 kb. b. Density distribution of relative substitution rates among concatenated Ancestral Repeats (ARs) around 100 kb of each DHS element in our list, concatenated local NFRs around each DHS, concatenated global NFRs before filtering out trees with low and high substitution rates. c. Density distribution of relative substitution rates in the concatenated global NFRs before and after filtration step. The arrow depicts the change in the median distribution of substitution rate of global reference alignments before versus after filteringBack to article page
