Question
- A. Misconception avoided: Chromosome number changes in meiosis; gene variants are alleles. This matches Meiosis because students must describe that meiosis involves two cell divisions to form four gametes, each with a single set of chromosomes.
- B. Common misconception: Missing that chromosomes contain many genes. This would blur Genes vs chromosomes instead of testing Meiosis.
- C. Partial misconception: Saying a chromosome codes for one protein instead of identifying a gene. This misses the objective focus on describe that meiosis involves two cell divisions to form four gametes, each with a single set of chromosomes.
- D. Terminology mix-up: It moves into a neighbouring Unit 4.6 idea rather than Reproduction / Meiosis.
Answer
The correct option is Misconception avoided: Chromosome number changes in meiosis; gene variants are alleles. This matches Meiosis because students must describe that meiosis involves two cell divisions to form four gametes, each with a single set of chromosomes.. It is the only option that keeps Genes vs chromosomes separate and answers the approved learning objective in Meiosis.
Explanation
The correct option is Misconception avoided: Chromosome number changes in meiosis; gene variants are alleles. This matches Meiosis because students must describe that meiosis involves two cell divisions to form four gametes, each with a single set of chromosomes.. Misconception avoided: Chromosome number changes in meiosis; gene variants are alleles. This matches Meiosis because students must describe that meiosis involves two cell divisions to form four gametes, each with a single set of chromosomes. is correct because Chromosome number changes in meiosis; gene variants are alleles. The learning objective says students must describe that meiosis involves two cell divisions to form four gametes, each with a single set of chromosomes, so the answer must stay inside Meiosis. The alternative options are wrong because they either missing that chromosomes contain many genes., saying a chromosome codes for one protein instead of identifying a gene., or drift away from options should make scale explicit: section of dna versus long dna molecule..
Common mistake
Misunderstanding Meiosis Divisions
Students often think that meiosis involves only one cell division instead of two, leading to confusion about the number of gametes produced.
Emphasize that meiosis consists of two distinct divisions: meiosis I and meiosis II, which together result in four gametes, each containing a single set of chromosomes.
