Question
- A. Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. This matches Selective breeding because students must explain that selected parents are bred, then offspring with desired characteristics are bred over many generations.
- B. Common misconception: Explaining protein coding without naming the gene as the relevant section of DNA. This would blur DNA vs genes instead of testing Selective breeding.
- C. Partial misconception: Treating DNA as if it always means one gene. This misses the objective focus on explain that selected parents are bred, then offspring with desired characteristics are bred over many generations.
- 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: A DNA base sequence is the storage format; a gene is the named instruction unit. This matches Selective breeding because students must explain that selected parents are bred, then offspring with desired characteristics are bred over many generations.. It is the only option that keeps DNA vs genes separate and answers the approved learning objective in Selective breeding.
Explanation
The correct option is Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. This matches Selective breeding because students must explain that selected parents are bred, then offspring with desired characteristics are bred over many generations.. Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. This matches Selective breeding because students must explain that selected parents are bred, then offspring with desired characteristics are bred over many generations. is correct because A DNA base sequence is the storage format; a gene is the named instruction unit. The learning objective says students must explain that selected parents are bred, then offspring with desired characteristics are bred over many generations, so the answer must stay inside Selective breeding. The alternative options are wrong because they either explaining protein coding without naming the gene as the relevant section of dna., treating dna as if it always means one gene., or drift away from do not use dna, gene, and chromosome as interchangeable answers..
Common mistake
Selective breeding common mistake 1
Giving a vague answer instead of directly addressing: Explain that selected parents are bred, then offspring with desired characteristics are bred over many generations..
Answer by clearly explaining how to explain that selected parents are bred, then offspring with desired characteristics are bred over many generations..
