Variation and evolution
Question
- A. Correct contrast: Mitosis produces identical cells; meiosis produces genetically different gametes. This matches Selective breeding because students must explain benefits, risks and ethical issues of selective breeding when given appropriate information.
- B. Reversed contrast: Claiming mitosis produces gametes. This would blur Mitosis vs meiosis instead of testing Selective breeding.
- C. Over-broad contrast: Forgetting chromosome number is maintained in mitosis but halved in meiosis. This misses the objective focus on explain benefits, risks and ethical issues of selective breeding when given appropriate information.
- 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 benefits, risks and ethical issues of selective breeding when given appropriate information.. 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 benefits, risks and ethical issues of selective breeding when given appropriate information.. Correct contrast: Mitosis produces identical cells; meiosis produces genetically different gametes. This matches Selective breeding because students must explain benefits, risks and ethical issues of selective breeding when given appropriate information. is correct because Mitosis produces identical cells; meiosis produces genetically different gametes. The learning objective says students must explain benefits, risks and ethical issues of selective breeding when given appropriate information, 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
Selective breeding common mistake 1
Giving a vague answer instead of directly addressing: Explain benefits, risks and ethical issues of selective breeding when given appropriate information..
Answer by clearly explaining how to explain benefits, risks and ethical issues of selective breeding when given appropriate information..
