a

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

b

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

c

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

d

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.
