(d) Disappearance of nucleolus

  • (b), (a,) (d), (c)

  • (b), (a) (c), (d)

  • (a), (b) (c), (d)

  • (b), (c) (d), (a)

Answer

B.

(b), (a) (c), (d)

The correct sequence of events of meiosis are:
Synapsis in zygotene rightwards arrowCrossing over in pachytene rightwards arrowTerminalisation of chiasmata in diplotene rightwards arrow Disappearance of nucleolus in diakinesis.

The correct sequence of events of meiosis are:
Synapsis in zygotene rightwards arrowCrossing over in pachytene rightwards arrowTerminalisation of chiasmata in diplotene rightwards arrow Disappearance of nucleolus in diakinesis.
