Crossing over is important because it creates genetic variability.
<h3>What is crossing over?</h3>
It is the exchange of chromosomal segments between non-homologous chromosomes in a tetrad.
Since chromosomal segments contain genes at different loci, the exchange will increase the genetic variability of the new chromosomes.
Thus, the daughter cells carrying the recombined chromosomes will be genetically variable from not just the parent cell, but fellow daughter cells.

Answer:
don't send this message XD XD
The fallopian tube, to where it moves down to the uterus...
The correct answer is www.biojobs.net - www.higheredjobs.org - www.dnrjobs.gov. This is found by looking at the top level domain of the url (ex .com). Out of that list, net is least credible, org is 2nd most credible, and gov is most credible.
Hope this helps
