- Each of the following has a better chance of influencing genotype frequencies in small populations than in large populations, but which one has the greatest influence in small populations? Group of answer choices Non-random mating Natural selection Gene flow Genetic drift Mutation PreviousNextarrow_forwardGodfrey Hardy and Wilhelm Weinberg stated the principle of equilibrium to describe the genetic makeup of a population. The theory, also known as the Hardy-Weinberg principle of equilibrium, states that a population’s allele and genotype frequencies are inherently stable. Which of the following phenomena could disrupt this equilibrium? Mutations Selection pressure Migration All of the given choicesarrow_forwardWhich of the following terms are used to apply ONLY TO SELECTION, and never to just evolution. Choose all that apply.

- Which of these conditions should completely prevent the occurrence of natural selection in a population over time? Group of answer choices Variation between individuals is not heritable. The environment is changing at a relatively slow rate. The population lives in a habitat where there are no competing species present. The population size is large.arrow_forwardFive conditions are required to maintain the Hardy–Weinberg equilibrium in a population. Closed population Large population Random mating No net mutations No natural selection If any of these conditions is not being met, the allele frequencies in the population will change, leading to microevolution in the population.Match each of the following scenarios to the Hardy–Weinberg condition that is NOT being met:An increase in antibiotic resistance among bacteria exposed to antibiotics occurs. AnswerCaribou from one herd move to a new area and breed with caribou of a completely different herd. Answer Among eastern bluebirds, more brightly coloured males breed with more brightly coloured females. AnswerDue to overhunting, there is little genetic diversity in the current population of bearded vultures, which have all descended from a population of only 36 birds.
