Which of the following is an incorrect stage in the context of Prophase-$I$?

$S$ - Statement: Meiosis occurs during the formation of reproductive cells. $R$ - Reason: During meiosis,the genetic material replicates twice,and the cell divides twice.

Chromosome number is halved in meiosis during

Which one of the following stages corresponds to Mendel's law of independent assortment?

The structure formed by a pair of synapsed homologous chromosomes is called:

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