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.

nalin [4]

What is it about a person that could cause ordinarily beneficial traits to become so self-defeating?.
Gala2k [10]

You may have feelings of inadequacy when you can't have—or give your children—the kind of life that others seem to have. All of these situations and challenges can lead to stress, which in turn lead to the development of Self Defeating Behaviors (SBD).

<h3>What is  beneficial traits?</h3>
  • Beneficial traits are extremely varied and may contain anything from protective coloration to the ability to operate a new food source, to a change in size or constitution that might be useful in a certain environment.
  • Over time, these favorable traits become more common in the residents. Through this process of natural preference, favorable characteristics are transmitted through generations. Natural preference can lead to speciation, where one species gives rise to a new and distinctly different species.
  • The artificial section is the identification by humans of seductive traits in factories and animals, and the steps taken to enhance and memorialize those traits in future years.
