Vedclass · Answer

(A) The process of meiosis $I$ is divided into several stages within Prophase-$I$: Leptotene,Zygotene,Pachytene,Diplotene,and Diakinesis.During the Diplotene stage,the synaptonemal complex dissolves and the homologous chromosomes of the bivalents start to separate from each other except at the sites of crossovers.These $X$-shaped structures are called chiasmata.In the final stage of Prophase-$I$,which is Diakinesis,the terminalisation of chiasmata occurs,where the chiasmata move towards the ends of the chromosomes.
