5.1 Meiosis

• Meiosis transforms a diploid cell into four haploid cells.

  True
• How many divisions occur in meiosis?

  Two
• What is the first phase of meiosis I?

  Prophase I
• Arrange the phases of meiosis I in their correct order:

  1️⃣ Prophase I

  2️⃣ Metaphase I

  3️⃣ Anaphase I

  4️⃣ Telophase I
• At the end of Telophase I, two haploid cells are formed.
• Arrange the phases of Meiosis I in the correct order.

  1️⃣ Prophase I

  2️⃣ Metaphase I

  3️⃣ Anaphase I

  4️⃣ Telophase I
• In Anaphase I, homologous chromosomes move to opposite poles of the cell.


  True
• Arrange the phases of Meiosis II in the correct order.

  1️⃣ Prophase II

  2️⃣ Metaphase II

  3️⃣ Anaphase II

  4️⃣ Telophase II
• The cells produced in Meiosis II are ready to participate in fertilization without further division.

  True
• Crossing over occurs during Prophase I of meiosis.
• Meiosis reduces the chromosome number from diploid to haploid
• The chromosome number remains the same in mitosis.


  True
• What happens to paired chromosomes during Metaphase I?

  They line up at the metaphase plate
• Mitosis results in a chromosome number that remains diploid
• During Metaphase I, paired chromosomes line up at the metaphase plate
• Meiosis I reduces the chromosome number by half
• What separates during Anaphase II of meiosis?

  Sister chromatids
• What is the final outcome of Meiosis II in terms of chromosome number and cell count?

  Four haploid cells
• Genetic variation in meiosis is crucial for evolution and adaptation.


  True
• What is the primary function of meiosis?

  Produce gametes
• Match the cell division with its characteristics:

  Mitosis ↔️ Two diploid cells (2n)

  Meiosis ↔️ Four haploid cells (n)
• Meiosis reduces the chromosome number by half to produce haploid gametes
• Crossing over occurs during Prophase I.

  True
• Homologous chromosomes separate during Anaphase I.

  True
• Meiosis involves two successive divisions, resulting in four genetically identical diploid cells.

  False
• In meiosis, the chromosome number changes from diploid (2n) to haploid
• What is the key event that occurs during Prophase I of meiosis?

  Crossing over
• What is the outcome of Telophase I in terms of chromosome number and cell type?

  Two haploid cells
• Telophase II results in the formation of four haploid daughter cells with genetically distinct complements.


  True
• Meiosis II ensures that each haploid cell contains a unique genetic complement
• What are the two key processes in meiosis that contribute to genetic variation?

  Crossing over and independent assortment
• What happens during independent assortment in Meiosis I?

  Chromosomes align randomly
