The final stage of meiotic prophase-$I$ is ......

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 $II$
$A$. Diakinesis	$1$. Crossing over takes place
$B$. Pachytene	$2$. Terminalisation of chiasmata
$C$. Zygotene	$3$. Chromosomes align at equatorial plate
$D$. Metaphase	$4$. Pairing of homologous chromosomes

Codes:
$A \quad B \quad C \quad D$

Match the following stages of meiosis with their characteristic events:
$(a)$ Zygotene $(i)$ Terminalization
$(b)$ Pachytene $(ii)$ Chiasmata
$(c)$ Diplotene $(iii)$ Crossing over
$(d)$ Diakinesis $(iv)$ Synapsis
Select the correct option from the following:

Lampbrush chromosomes occur during which of the following stages?

The correct sequence of stages during the prophase-$I$ of meiosis is:

At which site does crossing over occur between the chromatids of homologous chromosomes?
