The number of chiasmata depends on the ........

Crossing-over occurs in the

Match the stages of meiosis in Column-$I$ to their characteristic features in Column-$II$ and select the correct option using the codes given below.

Column-$I$	Column-$II$
$(A)$ Pachytene	$(i)$ Pairing of homologous chromosomes
$(B)$ Metaphase-$I$	$(ii)$ Terminalisation of chiasmata
$(C)$ Diakinesis	$(iii)$ Crossing-over takes place
$(D)$ Zygotene	$(iv)$ Chromosomes align at equatorial plate

In meiosis,the daughter cells are not similar to that of parent because of

Arrange the following events of meiosis in the correct sequence:
$(i)$ Crossing over
$(ii)$ Synapsis
$(iii)$ Terminalisation of chiasmata
$(iv)$ Disappearance of nucleolus

The chromosome number is reduced in which phase of meiosis?
