Most parthenogenic organisms also reproduce sexually, while others reproduce only by asexual means. The difference in the frequency between the two progeny plant types developed by the auxin test allows the estimation of apomictic capacity of the selected parents. It causes ovaries to mature without fertilization and produces bigger fruits. The parthenogenesis is the best way of high rate of multiplication in certain insects, e.g., aphids.

Looks like you’ve clipped this slide to already. Parthenocarpy keeps the insects and pests away without using chemicals because there is no requirement of pollinating insects for the formation of fruits. It includes parthenogenesis in animals, in which the new individual develops from the unfertilized egg, and apogamy in certain plants, in which the generative tissue may be the sporophyte or the gametophyte. Parthenogenesis definition, development of an egg without fertilization. Ever since the advent of cloning, there have been arguments for and against this process. In apomictic parthenogenesis, common in plants, the diploid germ line cells (gametocytes) do not undergo meiosis to create gametes but rather undergo regular cell division, or mitosis; offspring are clones of the mother.
