Is a fundamental principle in population genetics that describes the relationship between the frequencies of alleles and genotypes in a population that is not evolving. It is based on the assumptions of large population size, random mating, no mutation, no migration, and no natural selection. A) Population Genetics. B) Mendelian Population. C) Genetic Drift. D) The Hardy-Weinberg principle of equilibrium. Show Answer Correct Answer: D) The Hardy-Weinberg principle of equilibrium. 3. Which scenario would natural selection most likely work on? A) A population of parakeets that have the same size beak. B) An island with lizards that all look alike and are all eating the same food. C) A population of salmon with different skin colors that attract mates. D) All of the insects in a certain desert that have the same adaptation for saving water. Show Answer Correct Answer: C) A population of salmon with different skin colors that attract mates. 4. Can bacteria reproduce in a way such that when you start out with two bacteria, you get five bacteria? Why or why not? A) Yes, because bacteria reproduce sexually, and can produce any number of offspring, just as humans do. B) No, because bacteria grow at an exponential rate. C) No, because when bacteria reproduce, they split into two parts, and two bacteria splitting would result in four bacteria followed by 8 bacteria. D) None of the above. Show Answer Correct Answer: C) No, because when bacteria reproduce, they split into two parts, and two bacteria splitting would result in four bacteria followed by 8 bacteria. 5.
