Answer:

Crossing over is the process by which genetic material is exchanged by non-sister chromatids during meiosis.

Crossing over results in a new combination of genetic information for the cell for a specific trait.

Crossing over ensures that organisms are not identical from generation to generation.

Genetic recombination allows for a variation in genetic material that is passed through the generations.
