Meiosis

• What is meiosis?

  A type of cell division producing four daughter cells
• What is the chromosome number in daughter cells produced by meiosis?

  Each has half the number of chromosomes
• In which type of cells does meiosis occur?

  Gamete-producing cells
• What type of gametes does meiosis produce?

  Genetically different haploid gametes
• What are the stages of meiosis?

  1. Parent cell is diploid (two sets of chromosomes)
  2. Each chromosome is copied
  3. Parent cell divides into two
  4. Four daughter cells are produced
  5. Each daughter cell has one set of chromosomes (haploid)
  6. Daughter cells are genetically different
• What is the chromosome set in daughter cells produced by meiosis?

  One set of chromosomes
• What is the significance of meiosis resulting in variation?

  It produces genetically different daughter cells
• What are daughter cells produced by meiosis called?

  Daughter cells
• Compare mitosis and meiosis.

  • Mitosis produces two daughter cells
  • Meiosis produces four daughter cells
  • Mitosis produces identical daughter cells
  • Meiosis produces genetically different daughter cells
  • Mitosis produces diploid cells
  • Meiosis produces haploid cells
  • Mitosis occurs in body cells
  • Meiosis occurs in gamete-producing cells
• Why is it important to spell mitosis and meiosis correctly?

  To avoid confusion between cell divisions
• What is the outcome of meiosis of a diploid parent cell?

  Four genetically different haploid daughter cells
• Why must meiosis occur before fertilization?

  To ensure gametes have half the chromosome number
• What is the difference between haploid and diploid cells?

  Haploid has one set, diploid has two sets

  Genetically different haploid gametes
• What are the stages of meiosis?

  1. Prophase I
  2. Metaphase I
  3. Anaphase I
  4. Telophase I
  5. Prophase II
  6. Metaphase II
  7. Anaphase II
  8. Telophase II
• How many daughter cells are produced at the end of meiosis?

  Four daughter cells
• What is the significance of genetic diversity in meiosis?

  It produces genetically different offspring
• If a cell has 46 chromosomes, how many chromosomes will each daughter cell have after meiosis?

  23 chromosomes
• What is the difference between meiosis and mitosis?

  • Meiosis produces four genetically different cells
  • Mitosis produces two genetically identical cells
  • Meiosis occurs in gamete-producing cells
  • Mitosis occurs in somatic cells
• What is the term for cells produced by meiosis?

  Daughter cells
• What is the role of meiosis in sexual reproduction?

  It generates gametes for fertilization
• Why is meiosis important for evolution?

  It increases genetic variation in populations
