6.1.2 Meiosis

• Meiosis is a type of cell division that produces gametes with half the normal chromosome
• The second division in meiosis separates the chromosomes into four genetically distinct daughter
• Crossing over occurs during Prophase I of meiosis I.


  True
• Order the phases of meiosis I

  1️⃣ Prophase I

  2️⃣ Metaphase I

  3️⃣ Anaphase I

  4️⃣ Telophase I
• What is the second stage of meiosis called?

  Meiosis II
• Telophase II results in four genetically distinct haploid daughter cells.
• Daughter cells are genetically distinct due to processes like crossing over
• Mitosis maintains the chromosome number in daughter cells.


  True
• Match the process with its purpose:

  Mitosis ↔️ Growth and repair

  Meiosis ↔️ Gamete production
• Meiosis I is the stage where the chromosome number is halved.

  True
• Phases of meiosis I in the correct sequence:

  1️⃣ Prophase I

  2️⃣ Metaphase I

  3️⃣ Anaphase I

  4️⃣ Telophase I
• Meiosis II produces four genetically unique haploid gametes
• In Metaphase II, chromosomes align at the metaphase plate.


  True
• What is the final outcome of meiosis II?

  Four haploid gametes
• Crossing over occurs during Metaphase I of meiosis.

  False
• The first division in meiosis reduces the chromosome number by half.


  True
• What is the first stage of meiosis called?

  Meiosis I
• In Metaphase I, homologous chromosome pairs line up along the metaphase plate.
• What happens to homologous chromosomes during Anaphase I?

  They are separated
• Meiosis ensures that gametes have half the normal chromosome number
• Sister chromatids are separated during Anaphase II.


  True
• What is the primary purpose of mitosis in multicellular organisms?

  Growth and repair
• What is the purpose of mitosis?

  Growth, repair, asexual reproduction
• In meiosis, daughter cells have half the chromosome number of the parent cell.
• Daughter cells in mitosis are genetically identical to the parent cell.


  True
• What is the outcome of meiosis?

  Four haploid gametes
• Crossing over occurs during Prophase I of meiosis I.
• What is the result of meiosis I?

  Two haploid daughter cells
• Phases of meiosis II in the correct sequence:

  1️⃣ Prophase II

  2️⃣ Metaphase II

  3️⃣ Anaphase II

  4️⃣ Telophase II
• Match the process with its effect on genetic diversity:

  Crossing Over ↔️ Creates new allele combinations

  Independent Assortment ↔️ Unique mix of chromosomes

  Random Fertilization ↔️ Multiplies genetic combinations
