Figure 13.6 Which of the following statements about nondisjunction is true? Nondisjunction only results in gametes with n+1 or n-1 chromosomes. Nondisjunction occurring during meiosis II results in 50 percent normal gametes. Nondisjunction during meiosis I results in 50 percent normal gametes. Nondisjunction always results in four different kinds of gametes.
Because of the ________ alignment of homologous chromosomes during meiosis, gametes can end up with _________ mixes of maternal and paternal chromosomes. a. unvarying; different b. unvarying; duplicate c. random; duplicate d. random; different
Nondisjunction can be caused by ________. a. crossing over in meiosis b. segregation in meiosis c. failure of chromosomes to separate during meiosis d. multiple independent assortments
Tetraploidy may result from: a. lack of cytokinesis in meiosis II b. nondisjunction in meiosis I c. lack of cytokinesis in mitosis d. nondisjunction in mitosis in the early embryo e. none of these
The part of meiosis that is similar to mitosis is_______. a. meiosis I b. anaphase I c. meiosis II d. interkinesis
What is happening during this phase of meiosis? A.)Mitosis is complete and 4 diploid daughter cells have been produced. B.)Telophase II C.)Meiosis II is complete and 4 haploid daughter cells have been produced. D.)Meiosis I is complete and 4 diploid daughter cells have been produced E.)Meiosis II is complete and 4 diploid daughter cells have been produced
Genetic variation from meiosis is generated during ________. a. both meiosis I and meiosis II b. meiosis II c. meiosis I
Meiosis is relatively rare and mitosis is relatively common. Which of the following makes meiosis different from mitosis? Meiosis produces DNA-less cells. We don't fully understand meiosis mechanisms. All gametes are diploid, whereas daughter cells from mitosis are haploid. The resulting cells (gametes) are haploid.
Though the stages of meiosis have the same names as the stages of mitosis, they exhibit fundamental differences. What are the main differences between the two processes? Meiosis differs from mitosis in that the number of chromosomes is halved and genetic variation is introduced in meiosis, but not in mitosis Meiosis differs from mitosis in that the number of chromosomes is halved and genetic variation is reduced in meiosis, but not in mitosis. Metaphase and telophase portions of meiosis and mitosis are the same. Meiosis and mitosis are also the same, except for the number of chromosomes. Anaphase I and anaphase are different. Prophase and telophase portions of meiosis and mitosis are the same. Meiosis II and mitosis are also the same and have the same number of chromosomes. Anaphase I and anaphase are different.
Which of the following statements regarding mitosis and meiosis is false? All the events unique to meiosis occur during meiosis I. Mitosis provides for growth and tissue repair. Meiosis provides for asexual reproduction. In mitosis, the chromosomes replicate only once in the preceding interphase.
Which of the following represents things that are equivelant? A) Two alleles for the same gene in a homologous chromosome pair B) The sequence of DNA in the two sister chromatids of a chromosome after meiosis 1 C) The number of homologous chromosomes per cell before and after meiosis 1 D) The number of chromosomes in each of the four daughter cells after meiosis 2
Which of the following differentiates meiosis from mitosis? mitosis is used for the repair of cells, whereas meiosis creates cells for sexual reproduction. In mitosis four identical daughter cells are produced, whereas two genetically different cells are produced in meiosis meiosis is a form of asexual division, whereas mitosis is a form of sexual division mitosis occurs in prokaryotic cells, whereas meiosis occurs in eukaryotic cells
