Crossing over has led to the construction of linkage map or genetic maps of chromosomes. 4. Linkage group and linear order of the genes help to reveal the mechanism and nature of the genes. 5. Crossing over plays a very important role in the field of breeding to improve the varieties of plants and animals. 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.
