Researchers placed males and females of two fish species together in aquarium tanks. one tank had natural light and the other had a monochromatic orange light. under normal light, the males of the two species appear quite different. however, under the monochromatic light little difference between the males of the two species can be observed. the researchers recorded the mate choices of the females in each tank. under normal light the females strongly preferred males of their own species. in monochromatic light, females chose mates indiscriminately. the hybrids that resulted of interspecies reproduction were both viable and fertile. based on the data, which description of genetic and phenotypic variation in the fish populations is most likely true?
