TA DO NOT OPEN EXAM UNTIL INSTRUCTED TO DO SO Multiple Choice Questions Please Read the Instructions First Check your pages. There are 17 pages in this exam. You are responsible for making sure that you have all the pages. This examination is worth 130 points. Write your name, ID#, and Lab. Section on your scantron. 1. Indicate your answers on the scantron sheet using a number 2 or test scoring pencil. Press heavily, don t stray out of the margins, and completely erase any changed answers. 2. If you think that a multiple choice question is ambiguous or confusing, use the gripe sheet at the end of the examination to explain the problem. 3. There are 45 multiple choice or true/false questions worth 2 points each. Fill-in Questions 1. Use pen only (no grade corrections for pencil or white out). 2. Write only one answer per question. You can elaborate on an answer, but you will not be given any credit if you write two different answers to the question. 3. Spelling rules: ½ credit for 2 3 letters wrong or transposed.

12 Short Answer and Fill In A B C D E F 46. Construct a cladogram using the lizard images above. Notice differences in limbs, tails, eyes, and head spines. Draw lines and use letters (instead of drawings) to show the position of each species on your cladogram. Make the most parsimonious cladogram with the images above. You do not need to list character states on the cladogram. Hint: Species E is now extinct. (6 pts) Answer: A D F C B E 47. Name one advantage and one disadvantage to a male that controls a harem. (2 pts) ancestor common to all 12
13 Advantage: higher relative fitness (passes more of his genes to future generations) Disadvantage: energetically costly to keep other males from mating with the females 48. In certain species of whiptail lizards, all individuals are females and they undergo parthenogenesis. What problem do these animals face if their environment changes drastically? (1 pt) They have no genetic diversity where some individuals of the species can survive environmental change. 49. What is the nature of the association between ants and aphids and how are ladybugs involved? (2 pts) Ants and aphids have a symbiotic (mutualistic) relationship where aphids provide a honeydew reward to ants. Ants protect aphids by driving off predatory ladybugs. 50. Insects often develop resistance to chemical pesticides. Such resistance may be coded by a single resistance allele (for example, in mosquitoes and houseflies). Consider a dominant resistant allele R and the recessive non resistant allele r in a population of 100 mosquitoes. The frequency of the R allele is 0.7 and the frequency of the r allele is 0.3. If the population is in Hardy Weinberg equilibrium, what would be the expected number of phenotypic resistant and non resistant mosquitoes in the next generation? You must show all your work to receive credit. (4 pts) Frequency of resistant allele = p = 0.7 (p 2 + 2pq) * 100 = number of mosquitoes with resistant phenotype [(0.7) 2 + 2(0.7)(0.3)] * 100 mosquitoes = 91 Frequency of non resistant allele = q = 0.3 q 2 * 100 = number of non resistant mosquitoes (0.3) 2 * 100 mosquitoes = 9 OR, subtract the frequency of the resistant allele calculated in the first part of the problem from the population total (100) to obtain the frequency of the non resistant allele. 51. Name one structure or feature of ophiuroids that distinguishes them from other classes within their phylum. (2 pts) Accept any of the following: Five narrow arms that are distinctly offset from the oral disk Locomotion by articulated arms No anus No suckers on tube feet Polychaeta Oligochaeta Hirudinea

One the cladogram above, label the first occurrence of each of the following: (6 pts) A. cephalization B. complete gut C. gastrulation D. incomplete gut E. metamerism F. tagmatization 15
16 56. a. Choose just one of the three pictures above and write the name of the life stage directly below the picture. (1 pt) sporocyst redia cercaria b. What type of reproduction produces these stages? (2 pts) asexual reproduction c. For the stage on the right, what is its habitat after it is released and where must it end up to continue to the next life stage? (2 pts) The cercaria are aquatic and must penetrate a second intermediate host (such as a fish) or encyst on vegetation to become a metacercaria. 57. List the developmental characteristics for protostomes and deuterostomes.
