When placed together in the same body of water, the two kinds of female mosquitofish exhibit exclusive breeding preferences. -Which two of the following have operated to increase divergence between mosquitofish populations on Andros? 1)improved gene flow 2)bottleneck effect 3)sexual selection 4)founder effect 5)natural selection
