Question
- A. Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Sexual and asexual reproduction because students must explain that asexual reproduction produces genetically identical offspring called clones and involves only mitosis.
- B. Reversed contrast: Calling a gene a whole chromosome. This would blur DNA vs genes instead of testing Sexual and asexual reproduction.
- C. Over-broad contrast: Explaining protein coding without naming the gene as the relevant section of DNA. This misses the objective focus on explain that asexual reproduction produces genetically identical offspring called clones and involves only mitosis.
- D. Unrelated contrast: It moves into a neighbouring Unit 4.6 idea rather than Reproduction / Sexual and asexual reproduction.
Answer
The correct option is Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Sexual and asexual reproduction because students must explain that asexual reproduction produces genetically identical offspring called clones and involves only mitosis.. 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 Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Sexual and asexual reproduction because students must explain that asexual reproduction produces genetically identical offspring called clones and involves only mitosis.. Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Sexual and asexual reproduction because students must explain that asexual reproduction produces genetically identical offspring called clones and involves only mitosis. is correct because DNA can contain many genes; a gene has a specific coding role. The learning objective says students must explain that asexual reproduction produces genetically identical offspring called clones and involves only mitosis, 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 Clones
Students often confuse asexual reproduction with sexual reproduction, thinking that clones can arise from sexual processes.
Clarify that asexual reproduction involves only one parent and results in genetically identical offspring, while sexual reproduction involves two parents and mixes genetic information.
