Fig. 4.

Genomic regions of introgression between An. funestus and An. parensis. Windows classified as introgressed between An. funestus and An. parensis with >90% probability are represented on each chromosome arm. Blue indicates introgression from An. funestus into An. parensis; red indicates introgression from An. parensis into An. funestus. Empty areas were classified either with lower confidence or as not introgressed. Approximate locations of common chromosomal inversions in An. funestus (3Ra, 3Rb, 3La, and 2Ra) are indicated by double-headed arrows. Centromeres are represented as black 1/4 circles. Hatching represents a masked region.
