What are the benefits and disadvantages of asexual?

MITOSIS was for : 1.Growth 2.Replace cells 3.Asexual reproduction -parenthogenesis:with mitosis .Off spring are produced with a fertilized egg -binary fission(bacteria) -fragmentation(house plants,algae) -budding(out growth on the parent) - spores(yeast,hydra).
