1 . Evolution occurs at the level of A) the individual genotype. B) the individual phenotype. C) environmentally based phenotypic variation. D) the population. 2. The ability to taste the chemical PTC (phenylthiocarbamide) is determined in humans by a dominant allele T , with tasters having the genotypes Tt or TT and nontasters having tt. If you discover that 36 percent of the members of a population cannot taste PTC, then according to the Hardy–Weinberg rule, the frequency of the T allele should be A) 0.4. B) 0.6. C) 0.64. D) 0.8. 3. Eukaryotic cells are thought to be derived from prokaryotic cells that underwent phagocytosis without digestion of the phagocytized cell. This mutualistic relationship is explained by the A) endosymbiotic theory. B) cell theory. C) evolutionary theory. D) parasite theory. 4. Which of the following statements about speciation is not true? A) A small founding population can be involved in speciation. B) Speciation always involves interruption of gene flow between different groups of organisms. C) The rate of speciation can vary for different groups of organisms. D) Speciation cannot occur in a single generation. 5. A gene in humans has two alleles, M and N, that code for different surface proteins on red blood cells. If you know that the frequency of allele M is 0.2, according to the Hardy–Weinberg rule, the frequency of the genotype MN in the population should be A) 0.16. B)
