Table 3.

Substitutions, insertions, and deletions in exons and introns of Trapeze pseudogenes

	Substitutions	Insertions	Deletions	Average insertion sizes, bp	Average deletion sizes, bp
Exons	803	44	82	1.3	8.3
Introns	481	21	9	1.8	2.7
Total	1,282	65	91	1.5	7.7

To enable comparisons between exons and introns, values for introns are adjusted to correct for the fact that the total size of introns is smaller than the total size of exons. Values for exons are absolute values. The value of DNA loss rate (D; see text) was, however, calculated across all exons and introns by using uncorrected values.
