Vedclass · Answer

(C) Meiosis is a reductional division that results in genetic variation. $1$. Crossing over occurs during the pachytene stage of prophase-$I$,where non-sister chromatids of homologous chromosomes exchange genetic material,leading to new combinations of genes. $2$. Synapsis is the pairing of homologous chromosomes during the zygotene stage of prophase-$I$. While synapsis is a prerequisite for crossing over,the actual genetic recombination that makes daughter cells dissimilar to the parent occurs due to crossing over. Since crossing over is the primary mechanism for genetic variation and it depends on synapsis,both processes contribute to the distinct genetic makeup of the daughter cells compared to the parent cell.

In meiosis,the daughter cells are not similar to the parent cell because of:
