The main benefit of crossing over is that it increases genetic diversity.
<h2>
Crossing over and 
Genetic Diversity</h2>
Crossing over ensures that the daughter cells produced are genetically more diverse than their parent cells. 
The exchange of chromosomal segments makes the chromosomes of the daughter cells to be more sophisticated than that of their parents.
Increased genetic diversity in daughter cells increases their chances of survival as more genes are present in their genomes that could potentially make them more adaptable to the environment. 
In summary, crossing over increases genetic diversity and genetic diversity increases the chances of survival in the face of changing environment.
