5.2 Meiosis and Genetic Diversity

    Cards (52)

    • What is meiosis defined as?
      Specialized cell division
    • In meiosis I, the parent cell divides into two daughter cells, each with the same number but different combinations of chromosomes
    • Order the processes that contribute to genetic diversity in meiosis
      1️⃣ Independent assortment
      2️⃣ Crossing over
    • Meiosis results in haploid cells, while mitosis produces diploid cells
    • Meiosis produces cells with half the normal number of chromosomes.

      True
    • What type of cells are produced in meiosis II?
      Haploid cells
    • Match the characteristics of meiosis and mitosis
      Meiosis ↔️ Two cell divisions
      Mitosis ↔️ One cell division
    • What is the purpose of meiosis in organisms?
      Sexual reproduction
    • Order the phases of meiosis I
      1️⃣ Prophase I
      2️⃣ Metaphase I
      3️⃣ Anaphase I
      4️⃣ Telophase I
    • What happens during metaphase I of meiosis I?
      Homologous chromosomes align
    • Meiosis results in genetic diversity through crossing over and independent assortment
    • Match the phases of meiosis I with their key events
      Prophase I ↔️ Crossing over occurs
      Metaphase I ↔️ Homologous chromosomes align
      Anaphase I ↔️ Homologous chromosomes separate
      Telophase I ↔️ Nuclear envelopes reform
    • In anaphase I, the reduction in chromosome number results in daughter cells with half the normal number of chromosomes
    • During Anaphase I, the chromosome number is reduced from diploid to haploid
    • What are the two processes that contribute to genetic diversity in meiosis?
      Crossing over and independent assortment
    • Mitosis produces two identical diploid cells

      True
    • Order the phases of Meiosis I
      1️⃣ Prophase I
      2️⃣ Metaphase I
      3️⃣ Anaphase I
      4️⃣ Telophase I
    • In Telophase II, cytokinesis results in four haploid cells
    • In Metaphase II, sister chromatids align at the metaphase plate
      True
    • During Anaphase II, sister chromatids separate and move to opposite poles
    • In which phase of meiosis does independent assortment occur?
      Metaphase I
    • Independent assortment ensures each gamete receives an identical combination of chromosomes
      False
    • Meiosis involves two cell divisions: Meiosis I and Meiosis II
    • Match the characteristic with the correct type of cell division:
      Number of Cell Divisions ↔️ Meiosis: Two, Mitosis: One
      Chromosome Number ↔️ Meiosis: Haploid, Mitosis: Diploid
      Purpose ↔️ Meiosis: Sexual Reproduction, Mitosis: Growth
      Genetic Variation ↔️ Meiosis: High, Mitosis: None
    • During Prophase I, homologous chromosomes pair up in a process called synapsis
    • Which phase of meiosis II involves the separation of sister chromatids?
      Anaphase II
    • Order the stages of meiosis II:
      1️⃣ Prophase II
      2️⃣ Metaphase II
      3️⃣ Anaphase II
      4️⃣ Telophase II
    • Anaphase I reduces the chromosome number from diploid to haploid
    • During which phase of meiosis does crossing over occur?
      Prophase I
    • Independent assortment occurs during Metaphase I of meiosis.
      True
    • Mitosis is essential for the growth and repair of multicellular organisms.

      True
    • During prophase I, homologous chromosomes pair up in a process called synapsis
    • What reforms during telophase I of meiosis I?
      Nuclear envelopes
    • Meiosis involves two successive cell divisions, while mitosis involves only one.
