BIO152 Sample Final Exam Questions 2) Who proposed that organisms could be organized into a great chain of being? A) Aristotle B) Lamarck C) Linnaeus D) Darwin E) Wallace Answer: A 4) Which of the following scientists argued that variation among individuals allows evolution to occur? A) Aristotle B) Lamarck C) Linnaeus D) Wallace Answer: D 5) Researchers have found fossils of Eocene horse species in Colorado. Deeper deposits contain smaller species, and more recent deposits contain larger species. How does this observation support the theory of evolution? A) It suggests that species are unchanging and of recent origin. B) It proves that environments have changed over time. C) It provides evidence that species change over time. D) It shows that all species are related to each other. E) It does not support the theory of evolution. Answer: C The following question(s) are based on information in Hopi E. Hoekstra, Kristen E. Drumm, and Michael W. Nachman, "Ecological Genetics of Adaptive Color Polymorphism in Pocket Mice: Geographic Variation in Selected and Neutral Genes," Evolution 58(6), 2004: 1329-41.

Figure 24.1 24) The figure above shows the distribution of pocket-mouse coat colors in several Arizona populations found either on light-colored granite substrate or on dark volcanic rock (dark substrate). The Melanocortin-1 receptor (Mc1r) alleles, D and d, differ by four amino acids. Mice with DD and Dd genotypes have dark coats, whereas mice with the dd genotype are light colored. What sort of genotype frequencies might you expect to find in the Xmas, Mid, and O'Neill populations? A) Xmas high DD frequency; Mid high Dd frequency, O'Neill high dd frequency B) Xmas high Dd frequency; Mid high DD frequency, O'Neill high dd frequency C) Xmas high Dd frequency; Mid high dd frequency, O'Neill high DD frequency D) Xmas high dd frequency; Mid high Dd frequency, O'Neill high DD frequency E) Xmas high dd frequency; Mid high DD frequency, O'Neill high Dd frequency Answer: E 25) Refer to Figure 24.1. In their investigation of natural selection on Mc1r alleles (the gene that determines coat color) in Arizona pocket mice, Hoekstra et al. determined the frequency of the D and d alleles in each population. They also determined the frequency of alleles for two neutral mitochondrial DNA genes (genes that do not affect and are not linked to coat color). Why did the researchers include the

mitochondrial DNA genes as part of their experimental design? A) Allele change for the neutral mitochondrial genes serves as an experimental group and gives information on any general background genetic difference among these populations. B) Allele change for the neutral mitochondrial genes serves as a
