  • ↵Processed pseudogenes that are continuous in sequence with insertions ≤60 bp.

  • ↵Processed pseudogenes that are disrupted by insertions (>60 bp).

  • ↵Number of processed pseudogenes + pseudogenic fragments per 1 Mb DNA.

  • ↵RSP4Y on chromosome Y is an isoform of RSP4X on chromosome X.

  • Correlation (chromosome size, number of processed pseudogenes) = 0.89,P < 1E-8.

  • Correlation (chromosome size, number of processed pseudogenes + fragments) = 0.89, P < 1E-8.
