(A) Crossing over is a biological process that occurs during meiosis,specifically in the pachytene stage of prophase-$I$. It involves the exchange of genetic material between non-sister chromatids of homologous chromosomes. This process leads to the formation of new combinations of alleles,which are known as recombinations. These recombinations,along with mutations,are the primary sources of genetic variation in sexually reproducing organisms,allowing for evolution and adaptation.
