What information did you include in your response?
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.

I mentioned that crossing over occurs during meiosis and involves the exchange of genetic material between non-sister chromatids. This process leads to a new combination of genetic information for a specific trait. I also stated that crossing over is necessary to ensure that organisms are not identical from generation to generation. Lastly, I noted that genetic recombination, which is facilitated by crossing over, allows for a variation in genetic material that is passed down through the generations.
