Question
Microevolution and Macroevolution Workshee 1. What is the term used to describe the changes in allele frequencies of a population over generations? Agenetic drift B. founder effect C. microevolution D. directional selection 2. A random alteration in the sequence of DNA nucleotides that provides a new variant allele is A. gene mutation. B. polymorphism C. gene frequency. D. disruption 3. If two adjacent populations of the same species show gene flow, then the two populations will A. become more similar in their gene pools. B. become isolated from each other C. develop into different species D. adapt to different conditions and become separate. 4. Which of the following is true about genetic drift? A. It is more likely to occur in a large population than in a small population. 8. It may lead to an allele becoming fixed in a population when its alternative allele is lost from the population. C. It increases the number of heterozygotes in a population. D. It increases the frequency of rare alleles in a population. 5. Which statement is NOT true about natural selection? irectional selection occurs when one extreme phenotype is favored over another different extreme phenotype B. Stabilizing selection favors an intermediate phenotype over either of the extreme phenotypes C. Disruptive selection favors both of the extreme phenotypes over the intermediate phenotype. D. Directional selection leads to improved selection in a stable environment. E. Disruptive selection leads to polymorphism, favoring different forms of the same species. 6. Which of the following is required for natural selection to occur in a population? A. variation in the population B. inheritance of variation through genetic differences C. differential reproduction so that the more fit individuals have more offspring that survive to reproduce D. accumulation of adaptive traits so that they increase in the population E. All of the choices are required.Explanation / Answer
