Vedclass · Answer

(D) The exchange of genetic material between non-sister chromatids of homologous chromosomes is known as crossing over.Crossing over occurs during the $Pachytene$ stage of Prophase-$I$ of Meiosis.During this stage,the bivalent chromosomes clearly appear as tetrads.Recombination nodules appear at the sites where crossing over occurs,which later leads to the formation of chiasmata in the subsequent $Diplotene$ stage.

In which stage does the exchange of genes occur at the site of chiasmata formation?
