Step-by-step solution
The correct matching of the sub-stages of Prophase I with their defining events is as follows: Leptotene: Compaction of chromosomes continues throughout this stage. Zygotene: Homologous chromosomes pair up (synapsis) and bivalents are formed. Pachytene: Recombination nodules appear and crossing over occurs. Diplotene: Dissolution of the synaptonemal complex occurs and X-shaped structures called chiasmata become visible. Diakinesis: The meiotic spindle is assembled to prepare the homologous chromosomes for separatio
