16 cards

  1. What does diploid mean?

    Having two sets of chromosomes.

  2. What does haploid mean?

    Having one set of chromosomes.

  3. How many chromosomes are in a human body cell?

    46.

  4. How many chromosomes are in a human gamete?

    23.

  5. What does meiosis do to the chromosome number?

    It halves it.

  6. How many cells does meiosis make from one cell?

    Four.

  7. Are the cells made in meiosis identical?

    No, they are all genetically different.

  8. Where does meiosis happen in a human?

    In the ovaries and the testes.

  9. What is formed when two gametes fuse?

    A zygote.

  10. Is a zygote haploid or diploid?

    Diploid.

  11. Why must gametes be haploid?

    To maintain the diploid number when gametes combine.

  12. How does meiosis cause variation?

    The chromosomes are shared out randomly between the gametes.

  13. Which type of division is used for growth and repair?

    Mitosis.

  14. A cell has 24 chromosomes. How many are in a gamete?

    12.

  15. How many different gametes can one person make?

    Over 8 million.

  16. Common mistake about meiosis?

    Saying that it makes two cells, or identical cells. It makes four different cells.
