Question
- A. Misconception avoided: Mitosis supports growth and repair; meiosis supports sexual reproduction. This matches Advantages and disadvantages of sexual and asexual reproduction (biology only) because students must explain that sexual reproduction produces variation in offspring.
- B. Common misconception: Forgetting chromosome number is maintained in mitosis but halved in meiosis. This would blur Mitosis vs meiosis instead of testing Advantages and disadvantages of sexual and asexual reproduction (biology only).
- C. Partial misconception: Claiming meiosis is used for body growth. This misses the objective focus on explain that sexual reproduction produces variation in offspring.
- D. Terminology mix-up: 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 Misconception avoided: Mitosis supports growth and repair; meiosis supports sexual reproduction. This matches Advantages and disadvantages of sexual and asexual reproduction (biology only) because students must explain that sexual reproduction produces variation in offspring.. 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 Misconception avoided: Mitosis supports growth and repair; meiosis supports sexual reproduction. This matches Advantages and disadvantages of sexual and asexual reproduction (biology only) because students must explain that sexual reproduction produces variation in offspring.. Misconception avoided: Mitosis supports growth and repair; meiosis supports sexual reproduction. This matches Advantages and disadvantages of sexual and asexual reproduction (biology only) because students must explain that sexual reproduction produces variation in offspring. is correct because Mitosis supports growth and repair; meiosis supports sexual reproduction. The learning objective says students must explain that sexual reproduction produces variation in offspring, so the answer must stay inside Advantages and disadvantages of sexual and asexual reproduction (biology only). The alternative options are wrong because they either forgetting chromosome number is maintained in mitosis but halved in meiosis., claiming meiosis is used for body growth., or drift away from distractors should contrast purpose, product, and chromosome number..
Common mistake
Mixing up variation with mutation
Students often think that the variation produced by sexual reproduction is the same as a mutation, and therefore describe it as a change in the DNA sequence rather than a combination of existing alleles.
Explain that variation in sexual reproduction comes from the random combination of gametes (different alleles) during fertilisation, not from new changes in the DNA sequence. Use the example of a red‑green colour‑blind parent and a normal parent producing offspring with different combinations of alleles, not new mutations.
