Caption: These microscopy images show that, in mosquitoes, the different alleles of the TEP1 gene confer different degrees of resistance to malaria: the midgut of a mosquito whose only functional allele is the "resistance" one (left) contains a number of dead malaria parasites (black dots), but very few live parasites (fluorescent green dots), whereas in another, genetically identical, mosquito with only the "susceptibility" allele turned on (right), parasite survival was much higher.
