Answer
During crossing over in Prophase I of meiosis, homologous chromosomes exchange genetic material at specific points called chiasmata. This results in the formation of recombinant chromatids with a unique combination of alleles. The benefit of crossing over is that it increases genetic diversity within a species, which can improve the species' ability to adapt to changing environments and increase its chances of survival.
