Vedclass · Answer

(B) is the correct answer. Meiosis is characterized by the process of crossing over,which occurs during the pachytene stage of prophase-$I$. Crossing over involves the exchange of genetic material between non-sister chromatids of homologous chromosomes,leading to genetic variation. Meiosis is a reductional division where a diploid $(2n)$ cell divides to form four haploid $(n)$ daughter cells,whereas mitosis is an equational division where the chromosome number remains unchanged.

List-$I$ (Sub Phases of Prophase-$I$)	List-$II$
$A$. Diakinesis	$I$. Synaptonemal complex formation
$B$. Pachytene	$II$. Completion of terminalisation of chiasmata
$C$. Zygotene	$III$. Chromosomes look like thin threads
$D$. Leptotene	$IV$. Appearance of recombination nodules
