Length distribution of the 36 044 gene extensions according to the SRR ≥ 2 rule. The 5′ and 3′ extensions for each gene have been separately considered. All followed the SRR ≥ 2 rule except for 2669 of genes near telomeres and centromeres, where information is incomplete and that were replaced by the median length of extensions in their chromosomes; most of them in the 40–50 Kb range.
