Question
- A. Definition boundary: DNA can contain many genes; a gene has a specific coding role. This matches Sexual and asexual reproduction because students must explain that sexual reproduction mixes genetic information and produces variation in offspring.
- B. Scale confusion: Calling a gene a whole chromosome. This would blur DNA vs genes instead of testing Sexual and asexual reproduction.
- C. Process confusion: Explaining protein coding without naming the gene as the relevant section of DNA. This misses the objective focus on explain that sexual reproduction mixes genetic information and produces variation in offspring.
- D. Evidence confusion: It moves into a neighbouring Unit 4.6 idea rather than Reproduction / Sexual and asexual reproduction.
Answer
The correct option is Definition boundary: DNA can contain many genes; a gene has a specific coding role. 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 Definition boundary: DNA can contain many genes; a gene has a specific coding role. This matches Sexual and asexual reproduction because students must explain that sexual reproduction mixes genetic information and produces variation in offspring.. Definition boundary: DNA can contain many genes; a gene has a specific coding role. This matches Sexual and asexual reproduction because students must explain that sexual reproduction mixes genetic information and produces variation in offspring. is correct because DNA can contain many genes; a gene has a specific coding role. 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 calling a gene a whole chromosome., explaining protein coding without naming the gene as the relevant section of dna., or drift away from when asking about genes, test a section of dna, protein coding, alleles, or inherited characteristics..
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.
