Adaptive potential of hybridization in mosquito species

A natural experiment created by insecticidal pressure to determine how the most important malaria vectors -- A. gambiae s.s. and A. coluzzii -- respond rapidly to environmental change has been conducted by researchers. Researchers sequenced the genomes of individual wild mosquitoes of each species from southern Ghana. The results reveal that transfer of a major insecticide resistance mutation resulted in replacement of over 3 million surrounding DNA bases of one to the other. This is especially ...
