Answer:

Crossing over ensures that organisms of the same parents have differences in genetic content making them unique in one way or the other.

Hence, a unique GAMETE that has been genetically recombined will be formed. When these gametes are fertilized (egg) or fertilizes (sperm), organisms that are genetically different from their parents are produced. This ensures genetic variation, which is a difference in the genetic content of organisms.
