In meiosis,the centromere divides during

Meiosis-$I$ is a reductional division. Meiosis-$II$ is an equational division because ...........

The longest phase of meiosis $I$ is ......

Give the name of the phases of meiosis,in which
$I.$ the chromosome number is reduced to haploid state
$II.$ the amount of $DNA$ is reduced to haploid state
The correct option is

The various stages of meiosis are given in Column-$I$. Match them with the characteristics of the various stages of meiosis 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-$I$	$ii$. Terminalization of chiasmata
$C$. Diakinesis	$iii$. Crossing over occurs
$D$. Zygotene	$iv$. Alignment at the equatorial plate

The enzyme $Recombinase$ is required at which stage of $Meiosis \ I$?
