Meaning of Parthenogenesis:
Usually an un-fertilised ovum develops into a new individual only after the union with the sperm or fertilisation but in certain cases the development of the egg takes place without the fertilisation. This peculiar mode of sexual reproduction in which egg development occurs without the fertilisation is known as the parthenogenesis (Gr., parthenos = virgin; genesis = origin).Types of Parthenogenesis:
The parthenogenesis may be of two types:
Natural Parthenogenesis:
In certain animals the parthenogenesis occurs regularly, constantly and naturally in their life cycles and is known as the natural parthenogenesis.
Artificial Parthenogenesis:
The eggs which always develop into the young individuals by the fertilisation sometimes may develop parthenogenetically under certain artificial conditions. This type of parthenogenesis is known as artificial parthenogenesis. The artificial parthenogenesis may be induced by various chemical and physical means.
