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.

Natalka [10]

There is competition among species when they jostle for scarce resources.

<h3>What is competition?</h3>

The term competition has to do with a situation in which members of the same species scramble for scarce resources.

The following are the definitions of the types of competition;

  • interference competition - An individual directly interacts and changes the way other individuals attain resources.
  • apparent competition - Individuals do not compete directly for resources, but are prey for the same predator.
  • exploitation competition -  Individuals interact indirectly while competing for common resources.
