Vedclass · Answer

(C) The process of meiosis $I$ involves several stages of prophase $I$. $1$. Leptotene: Chromosomes become visible. $2$. Zygotene: Synapsis occurs between homologous chromosomes. $3$. Pachytene: Crossing over takes place between non-sister chromatids. $4$. Diplotene: The synaptonemal complex dissolves,and the homologous chromosomes begin to separate from each other,except at the sites of crossovers. These $X$-shaped structures are known as chiasmata,which become clearly visible during this stage.

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

During which stage does the chiasmata become visible?
