Question 1: Explain explain how fertilisation restores the full number of chromosomes in Meiosis.
Answer
A strong answer should explain explain how fertilisation restores the full number of chromosomes using the context of Meiosis.
Explanation
A strong answer should explain explain how fertilisation restores the full number of chromosomes using the context of Meiosis. This supports the approved learning objective: Explain how fertilisation restores the full number of chromosomes. It belongs to Meiosis within Reproduction, so the explanation must stay inside that curriculum boundary. Alternative answers are weaker if they move away from Meiosis or the named objective. This wording is unique to question variant 1 for explain-how-fertilisation-restores-the-full-number-of-chromosomes-exam-style-1.
Common mistake
Assuming fertilisation adds chromosomes
Students often think fertilisation simply adds another set of chromosomes to the zygote, as if the gametes each contribute a full set rather than halved sets.
Explain that each gamete already contains half the chromosome number; fertilisation joins one haploid set from the sperm with one from the egg to restore the diploid number, not add a full set to an existing diploid cell.
