- What are the four required conditions for natural selection to occur?Natural selection and artificial selection or selective breeding can both cause changes in animals and plants. The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene. Changes in genetic traits have occurred over generations through both natural selection and selective breeding although the occur through different means. What characterizes only artificial selection? Choose all that apply. A) chickens that lay larger eggs are favored B) selection increases the chances of surviving C) selection make a species stronger and fit for survival D) selection favors the desired characters in the new organismsWhich of the following is NOT a characteristic of natural selection? a) Variation exists among individuals in a population b) Some individuals are better adapted to their environment than others c) Organisms evolve to fit a predetermined goal or plan d) The better-adapted individuals are more likely to survive and reproduce
- Which of the following is not true for natural selection to occur? a) there should be variation within the population b) individuals with some genotypes have more offspring than individuals with others c) more individuals are born than can survive d) only individuals with favored alleles survive e) variation between individuals should be explained by genetics rather than environmentWhich of the following is true about natural selection? a) It always results in the evolution of new traits b) It always results in the strongest individuals surviving c) It always results in the fittest individuals reproducing d) It always results in the best-adapted individuals survivingWhat result in adaptation comes from natural selection?
