Diakinesis

Vedclass · Answer

(B) The process of meiosis $I$ is divided into several stages. During the $Prophase-I$ stage,specifically in the $Diakinesis$ sub-stage,the chromosomes are fully condensed and the meiotic spindle is assembled to prepare the homologous chromosomes for separation. $Diakinesis$ is characterized by the terminalization of chiasmata,which means the chiasmata move towards the ends of the chromatids. Therefore,the correct option is $B$.

Column-$I$	Column-$II$
$1$. Leptotene	$p$. Homologous chromosomes are separated
$2$. Diakinesis	$q$. Nucleolus reappears
$3$. Pachytene	$r$. Chromosomes can be observed in a microscope
$4$. Anaphase-$I$	$s$. Nucleolus disappears
	$t$. Crossing over

List-$I$	List-$II$
$a$. Zygotene	$i$. Terminalization
$b$. Pachytene	$ii$. Chiasmata
$c$. Diplotene	$iii$. Crossing over
$d$. Diakinesis	$iv$. Synapsis

This stage is marked by the terminalization of chiasmata.
