Vedclass · Answer

(B) Chiasmata are the $X$-shaped structures that form between non-sister chromatids of homologous chromosomes during the $Diplotene$ stage of $Prophase-I$ of $Meiosis$. The formation of chiasmata is a result of crossing over. The number of chiasmata is directly proportional to the length of the chromosomes,as longer chromosomes provide more physical space and opportunities for genetic recombination events to occur.
