Vhich of the following best describes the likely results of the scientists' investigation of the fitness of the sticklebacks that were originally from a marine environment? The fitness of the sticklebacks from the marine environment increased because their chance of survival and reproduction is greater in the freshwater environment than in the marine environment. The fitness of the sticklebacks from the marine environment increased because their chance of survival and reproduction is less in the freshwater environment than in the marine B environment. The fitness of the sticklebacks from the marine environment decreased because their chance of survival and reproduction is greater in the freshwater environment than in the marine environment. The fitness of the sticklebacks from the marine environment decreased because their chance of survival and reproduction is less in the freshwater environment than in the marine D environment.

Question

The three-spined stickleback (Gasterosteus aculeatus) is a species of fish that has both marine and freshwater populations. There are genetic differences between the populations in the different environments. The graph shows the frequency of a certain allele in freshwater and marine populations of stickleback fish. In 1978, scientists studied how the fitness of marine sticklebacks would be affected if they were introduced into a freshwater environment. They collected 90 male and 90 female sticklebacks from a marine population and 10 male and 10 female sticklebacks from a freshwater population. The 200 sticklebacks were introduced into a freshwater environment that had no stickleback fish previously. Which of the following best describes the likely results of the scientists’ investigation of the fitness of the sticklebacks that were originally from a marine environment?
