- Of the ways that populations can evolve over time, is the only mechanism in which the environment selects for better adapted individuals whereas selects traits by random chance. genetic drift; natural selection natural selection; genetic drift genetic drift; gene flow gene flow; natural selectionAt 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. What process causes the population to change colors? artificial selection natural selection migration behavioral isolationNatural selection is based on all of the following except individuals who survive longer tend to have more offspring than those who die young genetic variation exists within populations Individuals adapt to their environments and, thereby, evolve populations tend to produce more offspring than the environment can support the best adapted individuals tend to reproduce more
- Which 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 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.Natural selection occurs when which of the following conditions are met? Individual organisms depend on each other to obtain available resources • Variations between individual organisms lead to differential survival chances Habitat and nutrient resources in an area are plentiful over a long period of time The conditions in an ecosystem support a wide range of living organisms
- Population divergence occurring as a result of females in a species consistently choosing males of a particular color is an example of ecological speciation Haldane's Rule genetic drift sexual selectionWhich 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 breedGenetic drift differs from gene flow in that Group of answer choices genetic drift occurs at a steady, but low, rate in all populations while gene flow is largely random event occurring in small populations. genetic drift is most likely to produce a loss of genetic diversity in a population whereas gene flow will often increase genetic diversity in a population. none of these choices adequately describe the difference between genetic drift and gene flow. genetic drift is based on female choice of particular mates but gene flow is largely a product of natural selection.
- Which of the following is the hypothesis that individuals who possess favorable traits are more likely to survive and reproduce than those who possess less favorable traits? genetic drift gene flow mutation natural selectionWhich of the following forces of evolution tends to slow down population divergence and prevent speciation? Group of answer choices Sexual selection Genetic drift Gene flow Mutation Natural selectionWhich 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.
