Vedclass · Answer

(D) The $Pachytene$ stage is the third stage of $Prophase-I$ in $Meiosis-I$.During this stage,the process of crossing over occurs between non-sister chromatids of homologous chromosomes.This process is facilitated by the appearance of recombination nodules at the sites where crossing over occurs.While synapsis (pairing of homologous chromosomes) begins in the $Zygotene$ stage,the bivalents or tetrads become clearly visible during the $Pachytene$ stage.Therefore,both the appearance of recombination nodules and the clear visibility of tetrads are characteristic events of the $Pachytene$ stage.

Column-$I$	Column-$II$
$(A)$ Pachytene	$(i)$ Pairing of homologous chromosomes
$(B)$ Metaphase-$I$	$(ii)$ Terminalisation of chiasmata
$(C)$ Diakinesis	$(iii)$ Crossing-over takes place
$(D)$ Zygotene	$(iv)$ Chromosomes align at equatorial plate

Which event occurs during the $Pachytene$ stage of $Meiosis-I$?
