Vedclass · Answer

(D) Meiosis is a reductional division that results in four genetically distinct daughter cells.$1$. Crossing over occurs during Prophase-$I$ of meiosis,which involves the exchange of genetic material between non-sister chromatids of homologous chromosomes,leading to genetic recombination.$2$. Independent assortment occurs during Metaphase-$I$,where homologous chromosome pairs align randomly at the metaphase plate,leading to different combinations of maternal and paternal chromosomes in the gametes.Therefore,both crossing over and independent assortment contribute to the genetic variation observed in the daughter cells.
