The beginning of which stage of prophase I is recognized by the dissolution of the synaptonemal complex and the tendency of the recombined homologous chromosomes of the bivalents to separate from each other except at the sites of crossovers?

Step-by-step solution

During prophase I of meiosis, the beginning of the diplotene stage is characterized by the dissolution of the synaptonemal complex. The recombined homologous chromosomes of the bivalents tend to separate from each other except at the sites of crossovers. These X-shaped structures formed during separation are called chiasmata. Answer: Diplotene
