Figure 3.

Schematic representation of the heterochromatin amount in the An. gambiae genome. (a) Relative proportions of mapped chromatin types and unmapped sequences in the assembly. PH--pericentric heterochromatin, IHc--compact intercalary heterochromatin, IHd--diffuse intercalary heterochromatin, PEU--proximal euchromatin, EU--euchromatin, UNK--"unknown chromosome." (b) Comparison of sizes and positions of islands of genomic divergence (IGD) and regions of pericentric heterochromatin (HET) in the X chromosome, the 2L arm, and 3L arm. Position of a putative centromere corresponds to 0 bp.
