Comparison of means and medians of exon and intron length in the genome of Apis mellifera. We applied COGNATE with default options (thus using the longest of each gene’s alternative transcripts) to the genome and gene annotation of Apis mellifera, version 4.5. The respective data were downloaded from NCBI7, 8 and constitute a RefSeq annotation, predicted by the NCBI Eukaryotic Genome Annotation Pipeline. Shown is the comparison between the mean and median values of the exon length and of the intron length per transcript in bp, respectively. COGNATE considered 10,733 transcripts, comprising of 76,276 exons and 65,543 introns. N = 10,733 for mean and median exon lengths and N = 10,240 for mean and median intron lengths. The means of exon lengths are 355.32 (medians) and 452.99 (means) bp, means of intron lengths are 613.08 (medians) and 1502.31 (means) bp. The primary data are provided in Additional file 3
