Step-by-step solution
During prophase I of meiosis: Zygotene is characterised by the pairing of homologous chromosomes (synapsis) accompanied by the formation of the synaptonemal complex. Pachytene is characterised by the appearance of recombination nodules, the sites at which crossing over occurs between non-sister chromatids of the homologous chromosomes. Diplotene is recognised by the dissolution of the synaptonemal complex and the tendency of the recombined homologous chromosomes of the bivalents to separate from each other except a
