________________________ Name PID Number BIOLOGY 201 SECTION 007 Drs. Willett and Reice FIRST MIDTERM SEPTEMBER 20, 2007 PLEASE WRITE YOUR NAME ON ALL PAGES. Keep your answers brief and to the point. Limit your written answers to the space provided. Excess writing is not appreciated and will not be graded. On quantitative problems show your calculations. 1. Fill in the blanks with a single correct answer. (20 Points, 2.5 points each) a. In one mating system, called ___________ polygyny, males gather in groups to display to females but do not guard females or resources. b. The form of natural selection imposed upon bacteria by antibiotics is a good example of _____________selection, which acts to shift the mean value of resistance in the population. c. Systema naturae was proposed by ______________ who thought that God directly created the present number of species. d. There are genetic elements called ______________ elements that replicate copies of themselves in the genome sometimes even at the expense of the individual organism’s fitness. e. One situation that results in alternate equilibria is ____________________________ selection under which selection favors the common phenotype in the population. f. The type of mutation called _______________ often result in frameshift mutations if they occur in protein coding DNA sequence. g. Sewall Wright proposed the _____________________________ theorem in which drift plays a large role in allowing movement between adaptive peaks. h. In small populations _________________ can cause decreases in fitness due to the un- masking of rare deleterious mutations. 2. Multiple Choice (24 points, 3 points each)-Circle completely one answer per question. a. Which of the following CANNOT be used for identifying adaptations in populations: 1. Correlations of traits with environmental conditions across several populations. 2. Functional studies of enzymatic rates showing correlations between activity and conditions experienced by that enzyme across species. 3. Convergent evolution in traits across species. 4. Determining the mid-parent regression of offspring phenotype on parental phenotype. 5. Comparing the phenotypic traits of survivors to non-survivors. b. Which of the following likely did NOT play a large factor in Darwin’s development of the idea of evolution by natural selection: 1. The law of succession. 2. Mendel’s laws of genetics 3. Malthus’ writings on population sizes and resource availability. 4.
