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: Dissolution of the synaptonemal complex occurs,and homologous chromosomes start to separate except at the sites of crossovers (chiasmata).$5$. Diakinesis: Terminalization of chiasmata occurs,and the chromosomes are fully condensed.Therefore,the correct sequence is Leptotene $\rightarrow$ Zygotene $\rightarrow$ Pachytene $\rightarrow$ Diplotene $\rightarrow$ Diakinesis.

The correct sequence of stages during the prophase-$I$ of meiosis is:
