(D) Crossing over is a biological process that occurs during the pachytene stage of prophase-$I$ of meiosis.It involves the exchange of genetic material between non-sister chromatids of homologous chromosomes.This process results in the formation of new combinations of alleles on the chromosomes,which is known as genetic recombination.Therefore,crossing over is responsible for the recombination of linked alleles,leading to genetic variation in the offspring.
