Crossing over, which occurs during prophase I of meiosis when the homologous pairs of chromosomes pair up, results in the non-sister chromatids of the homologous pairs of chromosomes exchanging pieces of chromosomes (DNA), so that each chromatid will have a combination of the mother's and the father's chromosomes. This results in genetic recombination and increases genetic diversity.
