Parthenogenesis is a form of asexual reproduction in which an unfertilized egg develops into a new individual.

It is a method in which a new individual developed without fertilization. Here, males do not have any role to play and only female gametes develop into new offspring.

Examples of plants showing parthenogenesis include honey bees, ants, birds. 

Automixis (automictic parthenogenesis) is a postmeiotic process in which a haploid cell may either duplicate its chromosomes or join with another haploid cell. In both cases, diploid zygotes develop and grow into diploid adults.

Thelytokous parthenogenesis, that is, the production of diploid daughters from unfertilized eggs, may involve various cytological mechanisms, each having a different impact on the genetic structure of populations.
