  1. Asexual Reproduction

  2. What is reproduction? • Reproduction is a process where an organism produces others of the same kind • There are two types of reproduction in living organisms: • Asexual • Sexual • What is the difference?

  3. Asexual reproduction • The new organism has genetic information that is IDENTICAL to its parent • Examples: Regeneration, budding, parthenogenesis

  4. Budding • New organisms are produced as a growth from the parent • Mostly in marine animals • E.g. corals, hydra yeast cell Coral Polyp Photo courtesy Jeffrey N. Jeffords http://oceanworld.tamu.edu/students/coral/coral1.htm

  5. Regeneration • Some animals can re-grow parts • Some of these animals can also grow new organisms from the pieces • Ex. some worms and sea stars

  6. Parthenogenesis • Organisms can be produced from unfertilized eggs • E.g. some fish, reptiles, amphibians and aphids. • Most of these species can switch between sexual and asexual reproduction (depending on conditions)

  7. Asexual Reproduction • It has both advantages and disadvantages- what are some you can think of?
