An average number of introns per gene was determined with respect to the number of all annotated genes in the genome. For a gene to be considered complete and canonical, at least one of the gene's transcripts had to be annotated with ATG starting the initial coding exon and the terminal coding exon ending with TAA, TAG or TGA.
