The species of freshwater fish (Salvelinus spp.) in the lakes of Switzerland, Scandinavia and Great Britain could interbreed but do not Almost every lake has a different form of these fish. What is the most likely reason don't these fish interbreed? (1 point) They are gametically isolated They are behaviorally isolated They are temporarily isolated They are geographically isolated

Answer 1

The most likely reason these freshwater fish do not interbreed is that they are behaviorally isolated. While they have the capability to interbreed genetically, variations in mating behaviors, spawning times, or preferences can prevent interbreeding between the forms in different lakes.
