<p> Name______Ch 13 quiz</p><p>1. What are homologous structures? Give an example of a pair of homologous structures. (1 point)</p><p>Homologous structures are features with different functions but are structurally similar due to common ancestry. Example is the wing of a bat and the paw of a cat</p><p>2. Evolution acts on the __individual______but affects the ______population______. (1 point)</p><p>3. Genetic drift resulting from a disaster that drastically reduces population size is called (1 point) A) natural selection. B) gene flow. C) the bottleneck effect. D) nonrandom mating. E) the founder effect. </p><p>4. Hardy-Weinberg equilibrium can be used to test (1 point) A) Likelihood of an offspring obtaining a trait from a parent B) Evolution within a population C) Amount of mutation in a population D) If a population is shrinking or growing</p><p>5. We talked about three types of selection that can alter variation within a population. Which type of selection selects for individuals at both extremes of a phenotypic range? (1 point)</p><p>A) Stabilizing B) Directional C) Diversifying 6. Explain frequency-dependent selection (2 points)</p><p>Frequency-dependent selection is a type of selection that maintains two or more phenotypic forms in a population. If either form becomes more prevalent or common, natural selection acts against that form.</p><p>7. What were two of the three key observations that Darwin made when coming up with his theory of evolution? (1 point)</p><p>Traits vary in a population Traits are inherited from parent to offspring More offspring are produced than the environment can support</p><p>8. What are three ways genetic variation is produced? (2 point) Genetic Drift Gene Flow Mutation Non-random mating Natural Selection</p>
