Campbell Biology Test Bank Chapter 13 Study Guide Graded A+ 1) If a horticulturist breeding gardenias succeeds in having a single plant with a particularly desirable set of traits, which of the following would be her most probable and efficient route to establishing a line of such plants? 2) Which of the following statements defines a genome? 3) Asexual reproduction occurs during which of the following processes? 4) Quaking aspen trees can send out underground stems for asexual reproduction. Sexual reproduction is not as common, but when it does happen, the haploid gametes have 19 chromosomes. How many chromosomes are in the cells of the underground stems? 5) Which of the following statements is correct in comparing sexual and asexual reproduction? 6) At which stage of mitosis are chromosomes usually photographed in the preparation of a karyotype? 7) Which of the following statements is true of a species that has a chromosome number of 2n = 16? 8) Eukaryotic sexual life cycles show tremendous variation. Which of the following characteristics do all sexual life cycles have in common? I. Alternation of generations II. Meiosis II. Fertilization IV. Gametes V. Spores 9) Which of the following processes occurs in a plant's sexual life cycle? 10) Which of the following statements describes an example of alternation of generations? 11) A particular organism has 46 chromosomes in its karyotype. Which of the following statements is correct regarding this organism? 12) A triploid cell contains three sets of homologous chromosomes. If a cell of a diploid species that normally has 42 chromosomes per cell is triploid, this cell would be expected to have which of the following sets of chromosomes? 13) Which of the following processes might produce a human zygote with 45 chromosomes? 14) In a human karyotype, chromosomes are arranged in 23 pairs. If we choose one of these pairs, such as pair 14, which of the following do the two chromosomes of the pair have in common? Refer to the life cycles illustrated in the figure below to answer the following questions. 15) Which of the life cycles is typical for animals? 16) Which of the life cycles is typical for plants and some algae? 17) Which of the life cycles is typical for most fungi and some protists? 18) In a life cycle such as that shown in part III of the figure above, if the zygote's chromosome number is ten, which of the following statements will be true? 19) Which of the following characteristics do homologous chromosomes exhibit? 20) Many organisms spend most of their life cycle in the diploid state. If meiosis produces haploid cells, how is the diploid number restored for these types of organisms? 21) Which of the following statements is correct regarding the human X chromosomes? 22) Which of the following statements correctly describes a karyotype? 23) If a cell has completed meiosis I and the first cytokinesis, and is just beginning meiosis II, which of the following is an appropriate description of its genetic contents? 24) The somatic cells of a privet shrub each contain a total of 46 chromosomes. How do the chromosomes of this plant differ from the chromosomes of humans, who also have a total of 46? 25) Which of the following statements describes the chromosomal makeup of each daughter cell after telophase of meiosis I? 26) How do cells at the completion of meiosis compare with cells that are in prophase of meiosis I? 27) Which of the following events happens at the conclusion of meiosis I? 28) During which of the following processes do sister chromatids separate from each other? 29) Which of the following processes occurs in meiosis but not in mitosis? 30) When chiasmata can first be seen in cells using a microscope, which of the following processes has most likely occurred?
