Vedclass · Answer

(D) The correct answer is $D$. Multivalents are associations of more than two homologous chromosomes during meiosis. They typically occur in organisms that are heterozygous for reciprocal translocations. In these individuals,segments of non-homologous chromosomes are exchanged,leading to a cross-shaped configuration (quadrivalent) during the pachytene stage of prophase-$I$ of meiosis,as the homologous regions attempt to pair.
