Additional file 1:

Physically and in silico mapped DNA markers in the An. gambiae, An. funestus, and An. stephensi genomes. The markers used for calculating inversion distances among An. stephensi, An. gambiae, and An. funestus are highlighted by yellow on 2R, green on 2L, teal on 3R and gray on 3L arms of An. gambiae. The genomic coordinates of polymorphic inversions are show for 2La and 2Rj in bold black, for 2Rb in green bold font, for 2Rc in red bold font, for 2Ru in blue bold font. The genomic coordinates of overlapping polymorphic inversions are show for 2Rd by underline and for 2Rbk in italic font.

Comparative mapping of the chromosomes X of An. gambiae, An. funestus, and An. stephensi. Arrows denote oriented conserved gene orders between An. gambiae and An. stephensi. Shaded divisions on the An. gambiae chromosome denote the genomic coordinates in this species. The centromere regions are shown by black circles at the end of the chromosomes.
