The appearance of recombination nodules on homologous chromosomes during meiosis characterizes:
- Bivalent
- Sites at which crossing over occurs
- Terminalization
- Synaptonemal complex
Solution
Prophase I in meiosis-I is divided into 5 subphases:
- In Pachytene there is recombination of chromosomes. This is accomplished by the formation of recombination nodule.
- There is chiasmata formation in Diplotene which depicts the past recombination event.
- Terminalisation takes place of chiasmata.
