CAIE IGCSE Biology 17.3 Meiosis Questions

Practise meiosis questions by identifying gamete production, applying diploid-to-haploid chromosome halving and explaining fertilisation restoring chromosome number.

Syllabus
2026–2028
Course
Biology 0610

Exam points

  • identify meiosis as gamete production rather than growth, repair or mitosis
  • calculate haploid gamete numbers from diploid chromosome counts in species examples
  • explain reduction division and fertilisation restoring chromosome number across generations

Sexual reproduction also occurs in humans.

Human male gametes are haploid.

State the name of the process that produces haploid male gametes.

Question 2

[Maximum number: 3]

Meiosis is another type of nuclear division.

Describe how the nuclei in cells produced by meiosis differ from the nuclei in cells produced by mitosis.
