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