Vedclass · Answer

(A) The diplotene stage of prophase-$I$ of meiosis is characterized by the dissolution of the synaptonemal complex.However,the homologous chromosomes do not separate completely at the sites of crossing over.These $X$-shaped structures are called chiasmata.Therefore,the diplotene stage is the stage where chiasmata become visible and can be counted.Since the reason explains why chiasmata are visible and countable at this stage,both statements are correct and the reason is the correct explanation.

$A$ : Chiasmata counting stage is diplotene.
$R$ : Dissolution of the synaptonemal complex occurs except at the sites of crossovers.
