During crossing over dna is exchanged between

WebDuring crossing over, a segment of DNA from one chromosome is exchanged with a corresponding segment from the other chromosome. This process creates new combinations of alleles on the resulting chromosomes, increasing the genetic diversity of the daughter cells. The significance of crossing over cannot be overstated.
