Answer:
the chronological order of events for the physical process of meiotic recombination would be:
Homologous chromosomes align in zygotene.
Recombination occurs between non-sister chromatids during the pachytene stage.
Crossovers of recombination are visible in the diplotene phase.
Homologous chromosomes partially separate but are still held together at joints called chiasmata.
Chiasmata are progressively broken as meiosis I is completed, corresponding to resolution of the recombination intermediates.
