Variation and evolution
Question
- A. Definition boundary: Mitosis produces identical cells; meiosis produces genetically different gametes. This matches Evolution because students must explain how variants with phenotypes best suited to an environment are selected.
- B. Scale confusion: Claiming mitosis produces gametes. This would blur Mitosis vs meiosis instead of testing Evolution.
- C. Process confusion: Forgetting chromosome number is maintained in mitosis but halved in meiosis. This misses the objective focus on explain how variants with phenotypes best suited to an environment are selected.
- D. Evidence confusion: It moves into a neighbouring Unit 4.6 idea rather than Variation and evolution / Evolution.
Answer
The correct option is Definition boundary: Mitosis produces identical cells; meiosis produces genetically different gametes. This matches Evolution because students must explain how variants with phenotypes best suited to an environment are selected.. It is the only option that keeps Mitosis vs meiosis separate and answers the approved learning objective in Evolution.
Explanation
The correct option is Definition boundary: Mitosis produces identical cells; meiosis produces genetically different gametes. This matches Evolution because students must explain how variants with phenotypes best suited to an environment are selected.. Definition boundary: Mitosis produces identical cells; meiosis produces genetically different gametes. This matches Evolution because students must explain how variants with phenotypes best suited to an environment are selected. is correct because Mitosis produces identical cells; meiosis produces genetically different gametes. The learning objective says students must explain how variants with phenotypes best suited to an environment are selected, so the answer must stay inside Evolution. 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
Evolution common mistake 1
Giving a vague answer instead of directly addressing: Explain how variants with phenotypes best suited to an environment are selected..
Answer by clearly explaining how to explain how variants with phenotypes best suited to an environment are selected..
