In which sub-stage of Prophase-$I$ does the "Bouquet stage" occur?

When the number of chromosomes is already reduced to half in the first reductional division of meiosis,what is the necessity of the second meiotic division?

Which of the following is known as reductional division?

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

During gamete formation,the enzyme recombinase participates during

Identify the meiotic stage in which the homologous chromosomes separate while the sister chromatids remain associated at their centromeres.
