Question
- A. Misconception avoided: Mitosis supports growth and repair; meiosis supports sexual reproduction. This matches Selective breeding because students must explain that inbreeding can make some breeds prone to disease or inherited defects.
- B. Common misconception: Forgetting chromosome number is maintained in mitosis but halved in meiosis. This would blur Mitosis vs meiosis instead of testing Selective breeding.
- C. Partial misconception: Claiming meiosis is used for body growth. This misses the objective focus on explain that inbreeding can make some breeds prone to disease or inherited defects.
- D. Terminology mix-up: It moves into a neighbouring Unit 4.6 idea rather than Variation and evolution / Selective breeding.
Answer
The correct option is Misconception avoided: Mitosis supports growth and repair; meiosis supports sexual reproduction. This matches Selective breeding because students must explain that inbreeding can make some breeds prone to disease or inherited defects.. 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 Misconception avoided: Mitosis supports growth and repair; meiosis supports sexual reproduction. This matches Selective breeding because students must explain that inbreeding can make some breeds prone to disease or inherited defects.. Misconception avoided: Mitosis supports growth and repair; meiosis supports sexual reproduction. This matches Selective breeding because students must explain that inbreeding can make some breeds prone to disease or inherited defects. is correct because Mitosis supports growth and repair; meiosis supports sexual reproduction. The learning objective says students must explain that inbreeding can make some breeds prone to disease or inherited defects, so the answer must stay inside Selective breeding. 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..
