Vedclass · Answer

(C) The figure shows homologous chromosomes that have undergone crossing over,as evidenced by the exchange of segments between non-sister chromatids. Crossing over is the characteristic feature of the Pachytene stage of Prophase-$I$ in Meiosis. During this stage,the bivalent chromosomes clearly appear as tetrads,and the recombination nodules facilitate the exchange of genetic material.

Column $I$	Column $II$
$(a)$ Prophase-$I$	$(p)$ Nucleolus and nuclear membrane reappear
$(b)$ Metaphase-$I$	$(q)$ Longest phase
$(c)$ Anaphase-$I$	$(r)$ Homologous chromosomes align at the equatorial plate
$(d)$ Telophase-$I$	$(s)$ Number of chromosomes reaching each pole is half of the original cell

At the end of which stage of Prophase-$I$ do homologous chromosomes appear as shown in the figure?
