1. Parthenogenesis

   Parthenogenesis (; from the Greek παρθένος, parthénos, 'virgin' + γένεσις, génesis, 'creation') is a natural form of asexual reproduction in which growth and development of embryos occur in a gamete (egg or sperm) without combining with another gamete (e.g., egg and sperm fusing). In animals, parthenogenesis means development of an embryo from an unfertilized egg cell. In plants, parthenogenesis is a component process of apomixis. In algae, parthenogenesis can mean the development of an embryo from either an individual sperm or an individual egg.Parthenogenesis occurs naturally in some plants, algae, invertebrate animal species (including nematodes, some tardigrades, water fleas, some scorpions, aphids, some mites, some bees, some Phasmatodea and parasitic wasps) and a few vertebrates (such as some fish, amphibians, reptiles and birds). This type of reproduction has been induced artificially in a few species including fish, amphibians, and mice.Normal egg cells form in the process of meiosis and are haploid, with half as many chromosomes as their mother's body cells. Haploid individuals, however, are usually non-viable, and parthenogenetic offspring usually have the diploid chromosome number. Depending on the mechanism involved in restoring the diploid number of chromosomes, parthenogenetic offspring may have anywhere between all and half of the mother's alleles. In some types of parthenogenesis the offspring having all of the mother's genetic material are called full clones and those having only half are called half clones. Full clones are usually formed without meiosis. If meiosis occurs, the offspring will get only a fraction of the mother's alleles since crossing over of DNA takes place during meiosis, creating variation. Parthenogenetic offspring in species that use either the XY or the X0 sex-determination system have two X chromosomes and are female. In species that use the ZW sex-determination system, they have either two Z chromosomes (male) or two W chromosomes (mostly non-viable but rarely a female), or they could have one Z and one W chromosome (female). Parthenogenesis does not apply to isogamous species.

1. parthenogenesis

   Parthenogenesis is a type of asexual reproduction in which the offspring develops from unfertilized eggs. This phenomenon occurs in certain insects, spiders, reptiles, crustaceans, fish, and plants, allowing a single parent to reproduce without the involvement of a male. It results in the offspring being genetically identical to the parent, except for rare mutations.

Webster DictionaryRate this definition:0.0 / 0 votes

1. Parthenogenesisnoun

   the production of new individuals from virgin females by means of ova which have the power of developing without the intervention of the male element; the production, without fertilization, of cells capable of germination. It is one of the phenomena of alternate generation. Cf. Heterogamy, and Metagenesis

2. Parthenogenesisnoun

   the production of seed without fertilization, believed to occur through the nonsexual formation of an embryo extraneous to the embrionic vesicle

3. Etymology: [Gr. parqe`nos a virgin + E. genesis.]

1. Parthenogenesis

   Parthenogenesis is a 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 and is a component process of apomixis. Gynogenesis and pseudogamy are closely related phenomena in which a sperm or pollen triggers the development of the egg cell into an embryo but makes no genetic contribution to the embryo. The rest of the cytology and genetics of these phenomena are mostly identical to that of parthenogenesis. The word parthenogenesis comes from the Greek παρθένος, parthenos, meaning "virgin" and γένεσις, genesis, meaning "birth". The term is sometimes used inaccurately to describe reproduction modes in hermaphroditic species that can reproduce by themselves because they contain reproductive organs of both sexes in a single individual's body. Parthenogenesis occurs naturally in many plants, some invertebrate animal species and a few vertebrates. This type of reproduction has been induced artificially in a few species including fish and amphibians.

1. Parthenogenesis

   name given to asexual reproduction, that is, to reproduction of plants or animals by means of unimpregnated germs or ova.

1. Parthenogenesis

   A unisexual reproduction without the fusion of a male and a female gamete (FERTILIZATION). In parthenogenesis, an individual is formed from an unfertilized OVUM that did not complete MEIOSIS. Parthenogenesis occurs in nature and can be artificially induced.

1. Parthenogenesis

   reproduction by direct growth of germs from egg-cells without fertilization by the male element: as in plant lice, gall wasps, etc.

Examples of parthenogenesis in a Sentence

1. Oliver Ryder:

   This is truly an amazing discovery, we were not exactly looking for evidence of parthenogenesis, it just hit us in the face. We only confirmed it because of the normal genetic studies we do to prove parentage. Our results showed that both eggs possessed the expected male ZZ sex chromosomes, but all markers were only inherited from their dams, verifying our findings.

2. Cala Gonone:

   The mother lives in the large pelagic tub with another female specimen. If confirmed by DNA analysis, it would be the world's first documented parthenogenesis documented by Mustelus Mustelus. Ispera, the name chosen for the little one, in Sardinian means hope and a birth in the [COVID-19] era it certainly is.
