Recombination between homologous chromosomes is completed by the end of
- Diakinesis
- Zygotene
- Diplotene
- Pachytene
Answer
(4) Pachytene
Solution
Crossing over between non-sister chromatids of homologous chromosomes takes place during pachytene, catalysed by recombinase.
By the end of pachytene, recombination is complete and the chromosomes remain linked at the sites of crossing over (seen as chiasmata in diplotene).
