anyone?

anonymous · Answer

Randon fertilization allows species to combine genetic information that might not combine with selective fertilization.

anonymous · Answer

random fertilization helps to prevent natural selection thus when  two organisms are mated on the bases of similarity or dissimilarity of characters then natural selection will occur and only a particular type of organisms will increase in number  reducing the genetic variability thus to prevent natural selection from operating it is necessary that random fertilization occurs in a population and evry organism gets an equal chance to survive

@BostonBlue why is this question still open? o-O I found another one similar to it that's from a year ago.. Here: http://openstudy.com/study#/updates/4fb1771de4b05565342782b0

Fusion of sperm and ovum, each having a unique combination of chromosomes, introduces further variation.
