Question
- A. Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. This matches Genetic inheritance because students must explain that most characteristics result from multiple genes interacting rather than single-gene inheritance.
- 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 Genetic inheritance.
- C. Partial misconception: Treating DNA as if it always means one gene. This misses the objective focus on explain that most characteristics result from multiple genes interacting rather than single-gene inheritance.
- D. Terminology mix-up: It moves into a neighbouring Unit 4.6 idea rather than Reproduction / Genetic inheritance.
Answer
The correct option is Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. This matches Genetic inheritance because students must explain that most characteristics result from multiple genes interacting rather than single-gene inheritance.. It is the only option that keeps DNA vs genes separate and answers the approved learning objective in Genetic inheritance.
Explanation
The correct option is Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. This matches Genetic inheritance because students must explain that most characteristics result from multiple genes interacting rather than single-gene inheritance.. Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. This matches Genetic inheritance because students must explain that most characteristics result from multiple genes interacting rather than single-gene inheritance. 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 most characteristics result from multiple genes interacting rather than single-gene inheritance, so the answer must stay inside Genetic inheritance. 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
Misunderstanding Multiple Gene Interaction
Students often believe that characteristics are determined by a single gene, failing to recognize the role of multiple genes interacting.
Emphasize the concept of polygenic inheritance, where multiple genes contribute to a single trait, and provide examples to illustrate how these interactions can influence characteristics.
