Five stages of prophase include:-

2. Zygotene- synapsis occurs with synaptonemal complex being formed between homologous chromosomes.
3. Pachytene- crossing over of different chromatids
4. Diplotene- homologous chromosomes starts to separate from each other (disjunction), chiasmata appears (junction between chromosomes)
5. Diakinesis- chromosomes are fully condensed, nucleolus disappears and nuclear membrane disintegrates.
