IB Biology HL D2.1.9 Meiosis as reduction division
Practise sequencing meiosis events and explaining how two divisions reduce chromosome number while separating homologues and chromatids.
How this is tested
- order DNA replication, pairing, crossing over and chromosome separation in meiosis
- distinguish outcomes of meiosis I and meiosis II using chromosomes and DNA amount
- identify when homologous chromosomes or sister chromatids separate during meiosis
