These are distribution plots of gene structure of eukaroytes, the water flea Daphnia pulex (Daphx), the worm C.elegans (Worm), the mouse Mus musculus (Mouse), insects Drosophila melanogaster (DroMel), Dros. grimshawi (DroGri), and the honey bee Apis mellifera (Apis).

Gene components shown are exon length, intron length, exon counts per gene, CDS (spliced) and transcript (unspliced) lengths. The plots show log of frequencies for each statistic. For instance, Exon counts of 1 to 20 show Drosophila has about half its genes with one exon (5e-1), compared to 10% or less (1e-1) with 1 exon in Mouse, Worm and Daphnia. Drosophila genes have 15+ exons only rarely (1/1000), while other species have them at 2/100 rates.

Statistics are measured from gene features using eval-2.2.6 get_distribution.pl of Michael Brent's lab. See below the genome data sources, results and picture files.
