Figure 5From: Comparison of dot chromosome sequences from D. melanogaster and D. virilisreveals an enrichment of DNA transposon sequences in heterochromatic domainsDistribution of intron sizes in D. virilis compared to D. melanogaster. Introns from all D. virilis and D. melanogaster genes in the contigs studied were separated into groups based on size. The number on the x axis represents the minimal intron size; an intron is counted in that bin if it has that many bases or fewer. The y axis tallies the percent of total introns that fall into that bin. The two dot chromosomes have significantly similar intron size distributions, which differ significantly from those of the major chromosome arms.Back to article page
