Yоu hаve а friend whо wоrks in а local pet-store, where they use water fleas (Daphnia pulex) to feed a particular species of tropical fish. They comment on how the water fleas all look very similar, with the owner apparently commenting that they reproduce asexually under the conditions they are kept. Your friend wants to add a bit of variety (color, size, etc.) to the population to see if it heightens appeals to the fish and can be used as a food source for other species. A) Using what you know from class, how would you explain to your friend that shifting the water fleas to conditions that favor sexual reproduction, might help him achieve his goals? Consider the process itself when explaining your answer. [4pts] B) Why might the owner be using the current approach to breeding the water fleas? [2pts], and why (aside from the fish food preferences) might a change in breeding approach be of benefit to the population in the long-term? [2pts]
