IB Biology SL D2.1.11 Meiosis generates variation
Practise explaining how meiosis creates genetic variation through chromosome pairing, crossing over and separation into gametes.
How this is tested
- explain how crossing over between non-sister chromatids creates new allele combinations
- identify prophase I images using paired homologous chromosomes or chiasmata
- link independent separation of homologous chromosomes to variation among gametes
