Answer: crossing over allows for genetic variation

Explanation:

crossing over is the exchange of genes between two chromosomes which ends up resulting in non-identical chromatids that comprise the genetic material of gametes (sperm and eggs).

Basically crossing over makes the chromatids that are held together by a centromere, no longer identical to eachother which creates genetic variation.
