Vedclass · Answer

(D) The $Diplotene$ stage of $Meiosis-I$ is characterized by the dissolution of the synaptonemal complex and the tendency of the recombined homologous chromosomes to separate from each other except at the sites of crossovers.These $X$-shaped structures are called $Chiasmata$.In oocytes of some vertebrates,the $Diplotene$ stage can last for months or years,during which the chromosomes decondense and become active in transcription,a state known as the $Dictyotene$ stage.

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

In oocytes of some vertebrates,this stage can last for months or years.
