Question
- A. Definition boundary: Mitosis produces identical cells; meiosis produces genetically different gametes. This matches Advantages and disadvantages of sexual and asexual reproduction (biology only) because students must explain why organisms may reproduce by sexual or asexual methods depending on circumstances.
- B. Scale confusion: Claiming mitosis produces gametes. This would blur Mitosis vs meiosis instead of testing Advantages and disadvantages of sexual and asexual reproduction (biology only).
- C. Process confusion: Forgetting chromosome number is maintained in mitosis but halved in meiosis. This misses the objective focus on explain why organisms may reproduce by sexual or asexual methods depending on circumstances.
- D. Evidence confusion: It moves into a neighbouring Unit 4.6 idea rather than Reproduction / Advantages and disadvantages of sexual and asexual reproduction (biology only).
Answer
The correct option is Definition boundary: Mitosis produces identical cells; meiosis produces genetically different gametes. This matches Advantages and disadvantages of sexual and asexual reproduction (biology only) because students must explain why organisms may reproduce by sexual or asexual methods depending on circumstances.. It is the only option that keeps Mitosis vs meiosis separate and answers the approved learning objective in Advantages and disadvantages of sexual and asexual reproduction (biology only).
Explanation
The correct option is Definition boundary: Mitosis produces identical cells; meiosis produces genetically different gametes. This matches Advantages and disadvantages of sexual and asexual reproduction (biology only) because students must explain why organisms may reproduce by sexual or asexual methods depending on circumstances.. Definition boundary: Mitosis produces identical cells; meiosis produces genetically different gametes. This matches Advantages and disadvantages of sexual and asexual reproduction (biology only) because students must explain why organisms may reproduce by sexual or asexual methods depending on circumstances. is correct because Mitosis produces identical cells; meiosis produces genetically different gametes. The learning objective says students must explain why organisms may reproduce by sexual or asexual methods depending on circumstances, so the answer must stay inside Advantages and disadvantages of sexual and asexual reproduction (biology only). The alternative options are wrong because they either claiming mitosis produces gametes., forgetting chromosome number is maintained in mitosis but halved in meiosis., or drift away from meiosis questions must focus on gametes, halved chromosome number, sexual reproduction, or variation..
Common mistake
Choosing the wrong reproduction method
Students often assume that an organism will always use the method that gives the most offspring, ignoring environmental or resource constraints.
Explain that organisms select sexual or asexual reproduction based on factors such as resource availability, need for genetic variation, and environmental stability. Provide examples where asexual reproduction is favoured in stable conditions and sexual reproduction is favoured when change or competition requires variation.
