The flashcards below were created by user LaurenCamp29 on FreezingBlue Flashcards. What would you like to do?


  1. Reproductive process that produces 4 Haploid sex cells from 1 diploid body cell
    Meiosis
  2. What is produced in Meiosis?
    • Sex Cells
    • (sperm and egg)
  3. Cells having 1/2 the  # of Chromosomes as body cells
    Haploid Cells
  4. How are sex cells an example of Haploid Cells?
    Sperm and egg only have 23 chromosomes (not in pairs)
  5. The first cell of a new person?
    Zygote
  6. What are the 2 major steps of Meiosis?
    • Meiosis 1
    • Meiosis 2
  7. What are the 5 steps of Meiosis 1?
    • Interphase
    • Prophase 1
    • Metaphase 1
    • Anaphase 1
    • Telophase 1
  8. What happens in Meiosis?
    One 46 Chromosome breaks down into two 46 chromosomes which break down into two sets of 23 chromosomes each
  9. Similar Chromosomes aligned next to each other
    Prophase 1
  10. Similar Chromosomes
    Homologous chromosomes
  11. What happens during Prophase 1
    Crossing over occurs
  12. What happens during crossing over?
    Segments of DNA are exchanged
  13. Homologous chromosomes line up in the middle of the cell
    Metaphase 1
  14. Homologous chromosomes split and move to opposite sides of the cell
    Anaphase 1
  15. Cell prepares to undergo cytoplasm division
    Telophase 1
  16. Steps of Meiosis 2?
    (4)
    • Prophase 2
    • Metaphase 2
    • Anaphase 2
    • Telophase 2
  17. What is the results of Meiosis 2?
    4 Haploid Cells
  18. What are the results of Mitosis?
    2 Diploid cells
  19. What are the results of Meiosis for males/females?
    • Males:
    • 4 Sperm Cells

    • Females:
    • 1 egg and 3 polar bodies
  20. Mitosis  vs. Meiosis:
    MITOSIS:
    (7)
    • Mitosis:
    • Produces body cells
    • No crossing over
    • Diploid cells
    • 2 Indentical cells
    • No homologous pairs
    • 1 Divison
    • Same # of chromosomes
  21. Mitosis vs. Meiosis:
    MEIOSIS:
    (7)
    • Produces sex cells
    • Crossing over occurs
    • Haploid cells
    • 4 different cells
    • homologous pairs
    • 2 divisions
    • 1/2 # of chromosomes
  22. What are sex cells called?
    Gametes
