Question
- A. Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. This matches Sexual and asexual reproduction because students must explain that sexual reproduction mixes genetic information and produces variation in offspring.
- 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 Sexual and asexual reproduction.
- C. Partial misconception: Treating DNA as if it always means one gene. This misses the objective focus on explain that sexual reproduction mixes genetic information and produces variation in offspring.
- D. Terminology mix-up: It moves into a neighbouring Unit 4.6 idea rather than Reproduction / Sexual and asexual reproduction.
Answer
The correct option is Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. This matches Sexual and asexual reproduction because students must explain that sexual reproduction mixes genetic information and produces variation in offspring.. It is the only option that keeps DNA vs genes separate and answers the approved learning objective in Sexual and asexual reproduction.
Explanation
The correct option is Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. This matches Sexual and asexual reproduction because students must explain that sexual reproduction mixes genetic information and produces variation in offspring.. Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. This matches Sexual and asexual reproduction because students must explain that sexual reproduction mixes genetic information and produces variation in offspring. 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 sexual reproduction mixes genetic information and produces variation in offspring, so the answer must stay inside Sexual and asexual reproduction. 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 Genetic Mixing
Students often think that sexual reproduction guarantees variation in every offspring, rather than understanding that it mixes genetic information which can lead to variation.
Emphasize that while sexual reproduction mixes genetic information, the actual variation in offspring depends on the combination of alleles inherited from both parents.
