What is the best way to promote fusion between two related populations of mosquitofish, one of which lives in a predator-rich pond and the other of which lives in a predator-poor pond?

Build a canal linking the two ponds that permits free movement of mosquitofish, but not of predators.

Explanation:

On the Bahaman island of Andros mosquitofish populations live in various, now isolated, freshwater ponds that were once united. Currently some predator-rich ponds have mosquito fish that can swim in short, fast bursts, while other predator-poor ponds have mosquito fish that can swim continuously for a long time. When placed together in the same body of water, the two kinds of female mosquito fish exhibit exclusive breeding preferences.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
