The 20 questions

  1. What does meiosis halve in gametes?

    • Organelle count
    • Cell volume
    • Protein mass
    • Chromosome number

  2. What does fertilisation restore in a zygote?

    • Cytoplasm volume
    • Membrane tension
    • Ribosome count
    • Chromosome number

  3. How many gametes does one meiosis produce?

    • Two
    • Four
    • One
    • Eight

  4. How are gametes produced by meiosis related genetically?

    • Diploid copies
    • Exact clones
    • Genetically different
    • Genetically identical

  5. Which type of division does the new cell formed at fertilisation undergo?

    • Meiosis
    • Transpiration
    • Mitosis
    • Photosynthesis

  6. What happens to embryo cells as the embryo develops?

    • They fuse together
    • They lose chromosomes
    • They stop dividing
    • They differentiate

  7. Which specific detail of meiosis is excluded from GCSE requirements?

    • Chromosomal set
    • Cell division count
    • Stages of meiosis
    • Reproductive organs

  8. In which part of the body does meiosis occur?

    • Muscle tissue
    • Skin tissue
    • Liver tissue
    • Reproductive organs

  9. A human gamete has 23 chromosomes. How many does the fertilised egg have?

    • 12
    • 46
    • 92
    • 23

  10. How does an offspring formed by sexual reproduction compare to its parents?

    • Genetically identical
    • Genetically different
    • An exact clone
    • A maternal twin

  11. A cell with 8 chromosomes divides by meiosis. How many chromosomes does each gamete have?

    • 16
    • 8
    • 4
    • 2

  12. Why is meiosis essential before fertilisation in sexual reproduction?

    • Destroys organelles
    • Doubles mutations
    • Halves chromosomes
    • Stops cell growth

  13. What set of chromosomes is found in each gamete after meiosis?

    • Triple set
    • Single set
    • Quadruple set
    • Double set

  14. Why does a cell copy its genetic material before undergoing meiosis?

    • For gamete sets
    • To double volume
    • To reduce energy
    • To prevent mitosis

  15. How does mitosis maintain the chromosome number in daughter cells?

    • Halving DNA
    • Identical copies
    • Triple division
    • Random shuffling

  16. What type of cells does meiosis produce compared to mitosis?

    • Identical clones
    • Non-identical cells
    • Distant mutants
    • Bacterial spores

  17. Why are gametes from the same parent genetically unique?

    • Random assortment
    • Mutagenic radiation
    • Identical copying
    • Binary fission

  18. A cell has 16 chromosomes and produces gametes by meiosis. How many chromosomes does a fertilised egg from two such gametes have?

    • 4
    • 32
    • 16
    • 8

  19. Which process directly creates genetic variation during sexual reproduction?

    • Organelle decay
    • Cell elongation
    • Ribosomal shift
    • Random fertilisation

  20. What keeps chromosome numbers stable across generations in sexual species?

    • Diffusion and osmosis
    • Mutation and fission
    • Meiosis and fertilisation
    • Mitosis and cloning
