Figure 1.

The variability and association of chromosome-level Alu densities in different genomic regions. The data points are labeled with chromosome IDs. The intron (exon or intergenic) Alu density is calculated by the number of intron (exon or intergenic) Alus divided by the corresponding sequence length measured in Knt (see the Methods section for details).
