Parthenogenesis: In this article we will

In this article we will discuss about Parthenogenesis in Insects:- 1. Meaning of Parthenogenesis 2. Types of Parthenogenesis 3. Significance. 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 can occur without meiosis through mitotic oogenesis. This is called apomictic parthenogenesis . Mature egg cells are produced by mitotic divisions, and these cells directly develop into embryos. In flowering plants, cells of the gametophyte can undergo this process. The offspring produced by apomictic parthenogenesis are full clones of their mother, as in aphids. [23] Parthenogenesis involving meiosis is more complicated. In some cases, the offspring are haploid (e.g., male ... Parthenogenesis is a fascinating process in the natural world. It allows females to reproduce without males. What is parthenogenesis ? – Parthenogenesis Definition In most cases, an unfertilized ovum develops into a new individual only after fertilisation, however in other instances, the egg develops without fertilisation. This uncommon style of sexual reproduction in which egg development takes place without fertilisation is known as parthenogenesis (Greek: ; parthenos = virgin; = origin). A parthenogenone or parthenote is a parthenogenetic or parthenogenetic creature. The phenomena of ...
