\tMeiosis is responsible for the formation of *** cells or gametes that are responsible for sexual reproduction.\tIt activates the genetic information for the development of *** cells and deactivates the sporophytic information.\tIt maintains the constant number of\xa0chromosomes\xa0by halving the same. This is important because the chromosome number doubles after fertilization.\tIn this process independent assortment of maternal and paternal chromosomes takes place. Thus the chromosomes and the traits controlled by them are reshuffled.\tThe genetic mutation occurs due to irregularities in cell division by meiosis. The mutations that are beneficial are carried on by natural selection.\tCrossing over produces a new combination of traits and variations.
