Abstract

Analysis of the inversion polymorphism of Anopheles gambiae s.str. in The Gambia and surrounding zones of Senegal (Saloum and Casamance) shows, in samples from the central part of the study area, highly significant and temporally stable departures from Hardy-Weinberg equilibrium with deficits of the hetero-karyotypes. This situation and the general pattern of karyotype distribution are consistent with the hypothesis of two chromosomally differentiated populations of A. gambiae which show partial reproductive isolation and incomplete intergradation in the contact zone.
