Variation and evolution

Question

  1. A. Correct contrast: 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.
  2. B. Reversed contrast: Claiming mitosis produces gametes. This would blur Mitosis vs meiosis instead of testing Selective breeding.
  3. C. Over-broad contrast: 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.
  4. D. Unrelated contrast: It moves into a neighbouring Unit 4.6 idea rather than Variation and evolution / Selective breeding.

Answer

The correct option is Correct contrast: 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 Correct contrast: 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.. Correct contrast: 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..

Common mistake
