Assignment Help:

Diplotene:

  • The paired chromosomes repel each other and begin to separate.
  • Separation however, is not completed, because homologous chromosomes remain united by their point of interchange (Chiasmata).Each bivalent has at least one each such, the chromatids otherwise are separated.

Diakinesis:

  • During this phase the condensation of chromosomes reaches to its maximum.
  • At the same time separation of the homologous chromosomes(started during diplotene)is completed,
  • Nucleoli disappear.
