Asexual Reproduction…(Page 4) Asexual Reproduction is when a single organism produces offspring that have the same genetic material Some Examples: Budding (Hydra) Fragmentation (Some kinds of worms) Regeneration (Starfish) Binary Fission (Bacteria) Mitosis (Cell Division)

Benefits of Asexual Reproduction… Asexual Reproduction has benefits: Organisms can reproduce quickly Necessary for organisms can grow and develop Allows for repair of damage to the organism
