During crossing over, part of one chromosome is exchanged with another. Theories 4. With funk music. Crossing Over Crossing over, or recombination, is the exchange of chromosome segments between nonsister chromatids in meiosis. The amount of genetic variation is reduced. It increases the likelihood that daughter cells will contain different genetic combinations. This process is important in diploid organisms to ensure variation in the progeny. There is breakage of chromatid segments, exchange of nonsister chromatid segments and later their fusion in new places.
