Vedclass · Answer

(A) Chiasmata are $X$-shaped structures that form between homologous chromosomes during the diplotene stage of prophase-$I$ of meiosis. They represent the sites where crossing over has occurred,which involves the exchange of genetic material between non-sister chromatids of homologous chromosomes. As the synaptonemal complex dissolves,the homologous chromosomes begin to separate but remain attached at these crossover points,known as chiasmata.
