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.

Exam points

identify meiosis as gamete production and distinguish it from mitosis or growth
calculate haploid chromosome numbers from diploid parent cells in species examples
explain how reduction division makes genetically different haploid cells and fertilisation restores diploid number
