- Which statement illustrates the connection between natural selection and overreproduction of a population? a) populations vary in their inherited traits. b) species produce more offspring than can survive in the environment. c) individuals with inherited traits that promote survival tend to have more surviving offspring. d) individuals with traits that do not enhance survival cannot reproduce.arrow_forwardWhat characteristics make a particular kind of individual successful in the process of natural selection?arrow_forwardHow is natural selection different from “survival of the fittest”?arrow_forward
- Which 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 survivingarrow_forwardNatural 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 organismsarrow_forwardWhich 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 environmentarrow_forward
- Which of the following is not true of natural selection?(a) natural selection acts to preserve favorable traits and eliminate unfavorable traits (b) the offspring of individuals that are better adapted to the environment will make up a larger proportion of the next generation (c) natural selection directs the course of evolution by preserving the traitsacquired during an individual’s lifetime (d) natural selection Test Your Understanding acts on a population’s genetic variability, which arisesthrough mutation (e) natural selection may result in changes in allele frequencies in a populationarrow_forwardAccording to Darwin’s model of evolution, evolution can only occur if there is some variation present among the individual members of a population. Which statement best describes the source of this variation among members of a species? A) individuals will vary depending on geography and climate B) variation exists because not all genes will be expressed C) variation among individuals may arise as a result of mutations in the genetic code D) variation exists because different individuals will have different access to food and other resourcesarrow_forwardAccording to Darwin’s model of evolution, evolution can only occur if there is some variation present among the individual members of a population.
