Synapsis C. Repulsion between homologous chromosomes 3. Segregation D. Separation of homologous chromosomes 4. Diplotene

Step-by-step solution

Synapsis is the process during the zygotene stage of prophase I where homologous chromosomes are attracted to each other and align along their entire lengths. Crossing over occurs during the pachytene stage of prophase I. This is when non-sister chromatids of homologous chromosomes exchange genetic material, leading to genetic recombination. During the Diplotene stage of prophase I, the synaptonemal complex begins to break down, leading to a slight repulsion between homologous chromosomes. Segregation refers to the
