5. A population of viruses has an error-prone RNA polymerase.
Review Questions 1. True or False : If a mutation happens to a specific allele in an individual organism, evolution has occurred. 2. What do genetic drift, gene flow, and mutation all have in common?
3. What would help a population with inbreeding depression? (Choose all that apply.)
D. a selective pressure Driving Question 3: How does the gene pool of an evolving population compare to the gene pool of a nonevolving population? Why should you care? In early 1908, two mathematicians (G.H. Hardy and Wilhelm Weinberg) independently published their findings that genotype frequencies will not change in large randomly mating populations in which mutation, migration, and selection are absent. Remember that when genotype frequencies (and their underlying allele frequencies) don’t change, no evolution is occurring. The Hardy-Weinberg principle, then, specifies conditions under which evolution will not take place. It also provides a very useful tool with which to determine whether or not evolution is taking place in a population and, if so, how extensively. What should you know? To fully answer this Driving Question, you should be able to 1. List and describe the five conditions under which a theoretical population will be in Hardy-Weinberg equilibrium. 2. Explain the relationship between evolution and Hardy-Weinberg equilibrium. 3. Discuss whether Hardy-Weinberg conditions are likely to occur in natural populations, and explain what that means in terms of evolution. 4. Given the frequency of one allele, calculate the allele and genotype frequencies of a trait controlled by two alleles in a nonevolving population using the Hardy-Weinberg equation. Infographic Focus: The infographics most pertinent to the Driving Question are 14.5 and Up Close: Calculating Hardy-Weinberg Equilibrium. Test Your Vocabulary: Match the following definitions to the terms they describe: [HARDY-WEINBERG PRINCIPLE] The principle that, in a nonevolving population, both allele and genotype frequencies remain constant from one generation to the next. 1. List and describe the five conditions under which a theoretical population will be in Hardy-Weinberg equilibrium. List and describe the five conditions required for a theoretical population to be in Hardy-Weinberg equilibrium. The five conditions necessary for a population to be in Hardy-Weinberg equilibrium: 1. No mutations occur: new alleles are not introduced into the population.
2. No natural selection occurs: no selective pressure changes the allele frequency.
