Well, with asexual reproduction you are actually making a genetic copy or the original organism, almost like a clone -- their is no genetic difference between the org organism and its "offspring." 
With sexual reproduction the goal is to is to create 4 sex cell either sperm or egg cells. When cells split in sexual reproduction it enables for the off spring to have a great range of genetic diversity. The offspring will be a completly unique not like the mother or father but sharing traits for both. The main benefit of sexual reproduction is genetic diversity.
