Vedclass · Answer

(B) Prophase-$I$ of meiosis is a complex and long phase compared to the prophase of mitosis. It is subdivided into five distinct stages based on chromosomal behavior:$1$. Leptotene: Chromosomes become visible as compact threads.$2$. Zygotene: Pairing of homologous chromosomes occurs (synapsis).$3$. Pachytene: Crossing over takes place between non-sister chromatids of homologous chromosomes.$4$. Diplotene: The synaptonemal complex dissolves,and homologous chromosomes start to separate,revealing chiasmata.$5$. Diakinesis: The final stage where chromosomes are fully condensed and the nucleolus disappears,preparing for metaphase-$I$.Therefore,the correct sequence is Leptotene $\rightarrow$ Zygotene $\rightarrow$ Pachytene $\rightarrow$ Diplotene $\rightarrow$ Diakinesis.

The sub-stages of Prophase-$I$ are given in order.
