Parthenogenesis is regarded as a form of asexual reproduction since a zygote forms without the union between female and male gametes.


Parthenogenesis is a type of asexual reproduction in which a female gamete or egg cell develops into an individual without fertilization. Animals including most kinds of wasps, bees, and ants that have no sex chromosomes reproduce by this process. Some reptiles and fish are also capable of reproducing in this manner. Many plants are also capable of reproducing by parthenogenesis.


parthenogenesis (pär´thənōjĕn´əsĬs) [Gr.,=virgin birth], in biology, a form of reproduction in which the ovum develops into a new individual without fertilization. Natural parthenogenesis has been observed in many lower animals (it is characteristic of the rotifers), especially insects, e.g., the aphid.In many social insects, such as the honeybee and the ant, the unfertilized eggs give ...


Parthenogenesis (/ ˌ p ɑːr θ ɪ n oʊ ˈ dʒ ɛ n ɪ s ɪ s, -θ ɪ n ə-/; from the Greek παρθένος, parthenos, 'virgin' + γένεσις, genesis, 'creation') is a natural form of asexual reproduction in which growth and development of embryos occur without fertilization.In animals, parthenogenesis means development of an embryo from an unfertilized egg cell.


Parthenogenetic definition, development of an egg without fertilization. See more.


Parthenogenesis is a type of asexual reproduction and applies only to animals (the botanical counterpart is called apomixis; note that in this post, I will only be talking of animals, not plants, fungi, prokaryotes, bacteria, etc.).


Parthenogenesis reproduction from an ovum without fertilization, especially as a normal process in some invertebrates and lower plants, but also occurs in fish, reptiles, and amphibians. Asexual reproduction


Home » Biology » Parthenogenesis : Parthenogenesis . Parthenogenesis Parthenogenesis is a particular form of asexual reproduction in which females produce eggs that develop without fertilization. Parthenogenesis is seen in aphids, rotifers, and some other invertebrates, as well as in some plants.


Significance of Parthenogenesis: 1. The parthenogenesis serves as the means for the determination of sex in the honey bees, wasps, etc. 2. The parthenogenesis supports the chromosome theory of inheritance. 3. The parthenogenesis is the most simple, stable and easy process of reproduction. 4.


Parthenogenesis, a reproductive strategy that involves development of a female (rarely a male) gamete (sex cell) without fertilization. It occurs commonly among lower plants and invertebrate animals (particularly rotifers, aphids, ants, wasps, and bees) and rarely among higher vertebrates.
