(1 or more are correct). founder effect fitness allele frequencies bottleneck effect selective advantage/disadvantage cost/benefitThe equilibrium frequency of a deleterious allele under mutation-selection balance increases as: mutation rate increases strength of selection increases dominance increases none of the above
- Which of the following terms are used to apply ONLY TO SELECTION, and never to just evolution. Choose all that apply. Cost/benefit Selective advantage/disadvantage Founder effect Allele frequencies Fitness Bottleneck effectTRUE/FALSE. Disruptive selection creates alleles that increase genetic diversity in a population. If false explain why and if true explain whyWhich of the following is a FALSE statement? Inbreeding non-random mating will increase the number of homozygotes. Directional selection will decrease genetic variation. Migration will decrease genetic variation between populations. Genetic drift will decrease genetic variation between populations. Mutation will increase genetic variation.
- Which of the following is a TRUE statement? Non-random mating will increase the number of heterozygotes. Genetic drift within a population will increase genetic variation. Migration into the population will decrease genetic variation. Mutation will decrease genetic variation. Stabilizing selection will increase genetic variation.What type of selection occurs when one extreme population phenotype is favored? Group of answer choices genetic drift directional stabilizing disruptiveWhich type of selection is represented from a population of mice living in the forest where only dark colored fur survive? Disruptive Directional Stabalizing
- Which of the following is true about natural selection? Group of answer choices it acts on individuals it typically does not involve changes in genotype frequencies in a population it involves individuals willfully changing their genotype and/or phenotype in order to become better matched to their environment and leave more offspring it is a random process it involves humans increasing the frequency of desirable traits in a species by selecting which individuals breedWhich of the following statements correctly describes the conditions of microevolution? Select one: a. Mutations happen randomly, and the environment provides selective pressure. b. Mates are chosen based on specific traits, and the bottleneck effect is prevented. c. Genes to flow from one population to another, and random mating occurs. d. The population is closed, and individuals are not allowed to immigrate or emigrateAt the edge of the Arctic Circle, owls prey on field mice. Occasionally, in a litter of white field mice, a brown mouse appears. Because of greenhouse warming, the snow melts, changing the environment to shades of brown.
