Zygotene is marked by beginning of lateral pairing of homologous chromosomes at the chromosomal tips and its process along the length of chromosomes that is the formation of synaptonemal complex.
Pachytene is marked by completion of lateral pairing of homologous chromosomes along the entire length of chromosome and crossing over.
Diplotene is marked by breaking of synaptonemal complex, which holds the synapsed chromosomes together, which in turn causes separation of synapsed chromosomes all along their length except for the point of crossing over (chiasmata).
Diakinesis is marked by separation of homologous chromosomes at chiasmata as well.
