Variation and evolution
Question
- A. Definition boundary: Mitosis produces identical cells; meiosis produces genetically different gametes. This matches Selective breeding because students must explain the impact of selective breeding on food plants and domesticated animals.
- B. Scale confusion: Claiming mitosis produces gametes. This would blur Mitosis vs meiosis instead of testing Selective breeding.
- C. Process confusion: Forgetting chromosome number is maintained in mitosis but halved in meiosis. This misses the objective focus on explain the impact of selective breeding on food plants and domesticated animals.
- D. Evidence confusion: It moves into a neighbouring Unit 4.6 idea rather than Variation and evolution / Selective breeding.
Answer
The correct option is Definition boundary: Mitosis produces identical cells; meiosis produces genetically different gametes. This matches Selective breeding because students must explain the impact of selective breeding on food plants and domesticated animals.. It is the only option that keeps Mitosis vs meiosis separate and answers the approved learning objective in Selective breeding.
Explanation
The correct option is Definition boundary: Mitosis produces identical cells; meiosis produces genetically different gametes. This matches Selective breeding because students must explain the impact of selective breeding on food plants and domesticated animals.. Definition boundary: Mitosis produces identical cells; meiosis produces genetically different gametes. This matches Selective breeding because students must explain the impact of selective breeding on food plants and domesticated animals. is correct because Mitosis produces identical cells; meiosis produces genetically different gametes. The learning objective says students must explain the impact of selective breeding on food plants and domesticated animals, so the answer must stay inside Selective breeding. 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..
