Tajima’s D at varying distance from CDS for non-annotated sequence (red) versus a general TFs, b Promoters, c UTR, and d DHS regions, in African (blue) and non-African (green) populations. Neutral reference (non-annotated sequence at least 200 kb away from CDS) is illustrated by the dotted line. Shaded areas represent 95% confidence intervals, with Z-scores (non-annotated vs. annotation) shown per bin
