It is critical to divide the chromosome number in half prior to reproduction in order to make sure that there will be a balance amount of chromosome present.  There should be an equal number of chromosomes from each parent, if not, there will be some abnormalities.

Hence, it is very important that the offspring has half the number of chromosome.
