WebCrossing over is a concept of genetics that is often called recombination. It occurs during meiosis. Crossing over is the exchange of chromosomal segments between non-sister chromatids of homologous chromosomes during the production of gametes. So the correct option is "Two non-sister chromatids of homologous chromosomes".
