Reciprocal translocation

Vedclass · Answer

(D) During meiosis,homologous chromosomes pair up to form bivalents. When a reciprocal translocation occurs between non-homologous chromosomes,the segments are exchanged. During prophase-$I$ of meiosis,these translocated chromosomes attempt to pair with their homologous segments,leading to the formation of a cross-shaped structure known as a quadrivalent or multivalent. Therefore,reciprocal translocation is the cause of multivalent formation in diploid organisms.

In a diploid organism,the formation of a multivalent during meiosis is due to:
