WHAT IS ASEXUAL REPRODUCTION? Itis one of the two types of reproduction which splits an organism into two to produce another of the same species. In asexual reproduction, one organism produces offspring that are identical to itself and inherits the genes of that parent only. Itis reproduction which does not involve ploidy reduction, fertilization, gametes or sex cells.
FOUR TYPES OF ASEXUAL REPRODUCTION IN ANIMALS1) Fission or Budding One or more individuals are formed from the original. The new organism remains attached as it grows, separating from the parent organism only when it is mature.
2) Fragmentation A parent breaks into different fragments that eventually form new individuals. The splitting may or may not be "intentional"- it may occur due to man made or natural damage by the environment or predators this kind of organism´s may develop specific organs or zones that may be shed or easily broken off.
3) Regeneration When an animal that is capable of regeneration loses a body part, it can grow a replacement part. If the lost body part contains enough genetic information from the parent, it can regenerate into an entirely new organism. Echinoderms exhibit this type of reproduction.
4) Gemmules (internal budding) A parent releases a specialized mass of cells that can develop into an offspring. Gemmules are internal buds found in sponges that are the result of asexual reproduction, and are a response to a hostile environment.
