Question
- A. Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches Genetic inheritance because students must explain the terms gamete, chromosome and gene.
- B. Reversed cause: Treating DNA as if it always means one gene. This would blur DNA vs genes instead of testing Genetic inheritance.
- C. Missing link: Calling a gene a whole chromosome. This misses the objective focus on explain the terms gamete, chromosome and gene.
- D. Different process: It moves into a neighbouring Unit 4.6 idea rather than Reproduction / Genetic inheritance.
Answer
The correct option is Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. 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 cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches Genetic inheritance because students must explain the terms gamete, chromosome and gene.. Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches Genetic inheritance because students must explain the terms gamete, chromosome and gene. is correct because DNA is the molecule; a gene is a functional section of that molecule. 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 treating dna as if it always means one gene., calling a gene a whole chromosome., or drift away from when asking about dna, test molecular structure, base sequence, nucleotides, or genetic information storage..
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.
