Question

* ADA Normal a. No Spacing Heading 1 Heading 2 14. Examine the following scenario. A small island contains three separate populations of a single species of cherry tree. The seed size varies between trees. That is, some trees produce seeds that are all in the small size ranges, others produce seeds all in the middle size ranges, and others produce seeds in the large size ranges. A small population of mice is introduced to the island. The mice eat cherries and are the only predators on the cherry trees. When the mice eat a cherry, they completely digest it and the pit or seed inside it. The mice choose small and medium seeds and leave the largest seeds uneaten. a. Is natural selection is operating on the trees? Explain how? b. Is there any indication that members of the population differ in fitness? If no, what does this imply about the operation of natural selection? If yes, describe the difference in fitness. English (United States) Focus El

Answer 1

14 @ 6 Noi natural Selection is not obey ating on the frees. It is becaus artificially introduction of mice who selectively eat only small and medium seed leave largest Seed umeaten cause biased situation regarding growth of trees. Hence, as plants Clargest seed) are breffered its not a case of natural selection. No, there was no indication of differ in fitness among free population, because before idroduction of mice it is not said which free population die any tree population are dominant or recessive Init's densils Hence, it also im bly that population are not under matur al selection or any selection pressure as there fitness are equals, it also means population are in equilibrium
