Question
- A. Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Genetic inheritance because students must explain the terms gamete, chromosome and gene.
- B. Reversed contrast: Calling a gene a whole chromosome. This would blur DNA vs genes instead of testing Genetic inheritance.
- C. Over-broad contrast: Explaining protein coding without naming the gene as the relevant section of DNA. This misses the objective focus on explain the terms gamete, chromosome and gene.
- D. Unrelated contrast: It moves into a neighbouring Unit 4.6 idea rather than Reproduction / Genetic inheritance.
Answer
The correct option is Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Genetic inheritance because students must explain the terms gamete, chromosome and gene.. 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 Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Genetic inheritance because students must explain the terms gamete, chromosome and gene.. Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Genetic inheritance because students must explain the terms gamete, chromosome and gene. is correct because DNA can contain many genes; a gene has a specific coding role. The learning objective says students must explain the terms gamete, chromosome and gene, so the answer must stay inside Genetic inheritance. 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
Confusing gamete with chromosome
Students often say a gamete is the same as a chromosome, or that a chromosome is a gamete, mixing up the two terms.
Clarify that a gamete is a reproductive cell (sperm or egg) that contains a complete set of chromosomes, while a chromosome is a thread‑like structure made of DNA and protein that carries genes. A gamete contains many chromosomes, not just one.
