Question
- A. Correct cause and effect: Mitosis maintains chromosome number; meiosis halves chromosome number. This matches Advantages and disadvantages of sexual and asexual reproduction (biology only) because students must explain that humans can speed up natural selection through selective breeding to increase food production.
- B. Reversed cause: Claiming meiosis is used for body growth. This would blur Mitosis vs meiosis instead of testing Advantages and disadvantages of sexual and asexual reproduction (biology only).
- C. Missing link: Claiming mitosis produces gametes. This misses the objective focus on explain that humans can speed up natural selection through selective breeding to increase food production.
- D. Different process: It moves into a neighbouring Unit 4.6 idea rather than Reproduction / Advantages and disadvantages of sexual and asexual reproduction (biology only).
Answer
The correct option is Correct cause and effect: Mitosis maintains chromosome number; meiosis halves chromosome number. This matches Advantages and disadvantages of sexual and asexual reproduction (biology only) because students must explain that humans can speed up natural selection through selective breeding to increase food production.. It is the only option that keeps Mitosis vs meiosis separate and answers the approved learning objective in Advantages and disadvantages of sexual and asexual reproduction (biology only).
Explanation
The correct option is Correct cause and effect: Mitosis maintains chromosome number; meiosis halves chromosome number. This matches Advantages and disadvantages of sexual and asexual reproduction (biology only) because students must explain that humans can speed up natural selection through selective breeding to increase food production.. Correct cause and effect: Mitosis maintains chromosome number; meiosis halves chromosome number. This matches Advantages and disadvantages of sexual and asexual reproduction (biology only) because students must explain that humans can speed up natural selection through selective breeding to increase food production. is correct because Mitosis maintains chromosome number; meiosis halves chromosome number. The learning objective says students must explain that humans can speed up natural selection through selective breeding to increase food production, so the answer must stay inside Advantages and disadvantages of sexual and asexual reproduction (biology only). The alternative options are wrong because they either claiming meiosis is used for body growth., claiming mitosis produces gametes., or drift away from mitosis questions must focus on identical cells, growth, repair, asexual reproduction, or maintained chromosome number..
Common mistake
Confusing natural selection with selective breeding
Students often think that natural selection itself can be directly accelerated by humans, rather than recognising that selective breeding is a human‑led process that mimics natural selection to achieve desired traits.
Explain that natural selection is an unguided process acting on variation in a population, while selective breeding is a deliberate, human‑controlled method of choosing parents with favourable traits to produce offspring with those traits more quickly, thereby speeding up the effect of natural selection on food production.
