1. What is meiosis?
- A. A division producing two genetically identical diploid cells
- B. A reduction division producing genetically different haploid cells
- C. A process that doubles the chromosome number
- D. A type of cell death
2. What is meiosis involved in producing?
- A. Skin cells
- B. Gametes
- C. Muscle cells
- D. Red blood cells
3. A human diploid cell has 46 chromosomes. How many chromosomes will a gamete produced by meiosis from this cell contain?
- A. 46
- B. 92
- C. 23
- D. 69
4. Two haploid gametes, each with 23 chromosomes, fuse at fertilisation. How many chromosomes will the resulting zygote have, and why?
- A. 23, because gametes stay haploid after fusion
- B. 46, because fertilisation restores the diploid number by combining the two haploid sets
- C. 69, because the numbers are added and then a third set is created
- D. 11, because the number is halved again at fertilisation
5. A student claims that mitosis and meiosis both produce genetically identical cells. Explain why this is incorrect.
- A. It is correct — both processes always produce identical cells
- B. Only mitosis produces genetically identical cells; meiosis produces genetically different cells because of the way chromosomes are shared out during the reduction division
- C. Only meiosis produces identical cells; mitosis produces different cells
- D. Neither process produces genetically identical or different cells reliably
