front 13 Homologous chromosomes move toward opposite poles of a dividing cell during | back 13 meiosis I. |
front 14 How does the sexual life cycle increase the genetic variation in a species? | back 14 by allowing crossing over |
front 15 Independent assortment of chromosomes is a result of | back 15 the random and independent way in which each pair of homologous chromosomes lines up at the metaphase plate during meiosis I. |
front 16 Meiosis II is similar to mitosis in that | back 16 sister chromatids separate during anaphase |
front 17 Refer to the drawings in Figure 13.2 of a single pair of homologous chromosomes as they might appear during various stages of either mitosis or meiosis, and answer the following questions. | back 17 V only |
front 18 Which of these statements is false? | back 18 At sexual maturity, ovaries and testes produce diploid gametes by meiosis |
