Natural Parthenogenesis:

  • In certain animals, parthenogenesis occurs regularly, constantly and naturally in their life cycles and is known as the natural parthenogenesis.
  • Certain insects have no sexual phase and no males. 
  • They depend exclusively on the parthenogenesis for self-reproduction. 
  • This type of parthenogenesis is known as the complete parthenogenesis or obligatory parthenogenesis.
  • The life cycle of certain insects includes two generations, the sexual generation, and parthenogenetic generation, both of which alternate to each other. 
  • In such cases, the diploid eggs produce females and the unfertilized eggs produce males. 
  • This type of parthenogenesis is known as partial or incomplete or cyclic parthenogenesis.

Incomplete or cyclic parthenogenesis is found in those animals in which both sexual reproduction and parthenogenesis occur.
