Figure 4From: In depth annotation of the Anopheles gambiae mosquito midgut transcriptomeDensity of variants and expressed genes across 100-kb loci for the midgut transcripts for each Anopheles gambiae chromosomal arm. Variant density (blue filled graph) and gene density (red filled graph) shows variants across the entire genome with a tendency to decrease toward centromeric regions (“C” label). The gap region of no variants or expressed genes in Chromosome 3R corresponds to the heterochromatic region (orange arrow) near subdivision 35B/C. A normalized ratio of variants to gene density (blue line graph) shows regions of high polymorphism and regions of low polymorphism.Back to article page
