The next few questions refer to the following description.
On the Bahamian island of Andros,mosquitofish populations live in various,now-isolated,freshwater ponds that were once united.Currently,some predator-rich ponds have mosquitofish that can swim in short,fast bursts; other predator-poor ponds have mosquitofish that can swim continuously for a long time.When placed together in the same body of water,the two kinds of female mosquitofish exhibit exclusive breeding preferences.
-If one builds a canal linking a predator-rich pond to a predator-poor pond,then what type(s)of selection should subsequently be most expected among the mosquitofish in the original predator-rich pond,and what type(s)should be most expected among the mosquitofish in the formerly predator-poor pond?
