mode of asexual reproduction, in which embryo develops without fertilization.
a type of reproduction in which females produce offspring from unfertilized eggs.
The development of an individual from an egg without fertilization.
The production of offspring from unfertilized eggs. Special examples of it are arrhenotoky, pseudo-arrhenotoky, deuterotoky, and thelytoky.
( Genet .). Development of the egg without fertilization into a new individual. ( BCFT modif .).
The ability to produce offspring from unfertilised eggs.
Development of a new organism from an unfertilised egg.
development of the normal product of sexual reproduction from the female gamete alone.
the birth of organisms from unfertilized females.
development of a new individual from an unfertilized sex cell, occurring among lower plants and invertebrate animals
Asexual reproduction in which an unfertilized gamete (usually female) produces female offspring. Parthenogenesis vastly increases the speed at which a population can grow, though it results in a loss of genetic diversity among members of the population.
Development of a fruit without fertilization, so without formation of pips or seeds. The banana is a parthenocarpic fruit.
(par´ then oh jen´ e sis) [Gr. parthenos: virgin + genesis: source] • The production of an organism from an unfertilized egg.
(Greek, parthenos = virgin, genesis = birth) development of an unfertilized egg. Occurs mainly in plants but can also occur in animals. (More? Week 1 Abnormalities | Molecular Development - Epigenetics - Parthenogenesis)
The ability of a female organism to produce fertilized eggs without mating with a male.
the development of an organism from an unfertilized egg.
human conception without fertilization by a man
process in which an unfertilized egg develops into a new individual; common among insects and some other arthropods
A form of reproduction in which an unfertilized egg develops into a new individual (SMD); the process of inducing an unfertilized egg to initiate cell division.
The process by which the female of a species is able to reproduce without a male.
Reproduction without fertilisation (joining of egg and sperm).
The development from an egg without fertilization by a sperm. The egg cell may be haploid or diploid.
The development of young from unfertilized eggs laid by virgin females (queen or worker); in bees, such eggs develop into drones.
(n) [Gk. parthenos, virgin + GENESIS] Reproduction of organisms without conjunction of gametes of opposite sexes. Parthenogenetic (adj) . We are mixing metaphors with the ' parthenogenetic growth of usury.' The relationship is made by the fact of having two transactions taking place, the act of selling and the act of buying, which constitute trade. When money, and in this case false money, is allowed to make money on it- self, then you have usury. "Allah has permitted trade and forbidden usury." (Qur'an: 2:227)
Creation of an embryo using only an oocyte. The oocyte is stimulated chemically so that it retains 2 sets of chromosomes. (Human oocytes retain 2 sets of chromosomes until fertilized by a sperm; at that point, one set is ejected and the remaining set combines with the sperm chromosomes to form the new genome.)
par-tho-GEN-eh-sis Female reproduction without fertilization. 192
The laying of fertile eggs by a female without the need for fertilization by a male.
The method of reproduction whereby some species (of phasmids in particular) lay viable ova that have nonetheless not been fertilised. When an insect reproduces parthenogenically, they will only produce female young. This method of reproduction enables the species to exist in the absence of males.
the development of an organisms from an unfertilized egg. This process is relatively common in plants, but less so among animals. Some species of insects can produce large numbers of individuals which are diploid. Some species of lizards can also produce diploid progeny. Since a female parent is, in essence, cloning herself, parthenogenesis always produces only female offspring. Since no recombination of genetic material between parents occurs, genetic variation within populations that use parthenogenesis is limited. However, this process can result in quick repopulation of a devastated area in a short period of time especially if the population has been thinned such that mating encounters between males and females are rare.
Reproduction without male fertilization.
A form of nonsexual reproduction in which eggs are subjected to electrical shock or chemical treatment in order to initiate cell division and embryonic development.
A form of nonsexual reproduction . . . in which the female reproduces its kind without fecundation by the male.
The production of offspring by a female with no genetic contribution from a male.
The production of living organisms from unimpregnated eggs or seeds. 151
the development of young from unfertilized eggs. In honey bees the un-fertilized eggs produce drones.
partenogenesis] activation of an egg to induce reproduction without fertilization by a male gamete.
egg development without fertilization
Production of offspring by female animals from unfertilized ova having the same chromosome number (haploid or diploid) as the parent.
A form of reproduction where an egg develops without sperm. Parthenogenesis occurs commonly among insects and other arthropods. Artificially inducing parthenogenesis with human eggs may be a means to isolate stem cells from an embryo, without fertilization.
Form of nonsexual reproduction in which unfertilized ovum is artificially induced to develop into an embryo.
bisc333 Some fish, reptiles and insects are all female and reproduce by parthenogenesis- the offspring are all clones of the female
Process of reproduction by the development of an unfertilized egg.
Development of an egg without fertilization, which occurs at low levels in chickens and turkeys. Parthenogenic embryos usually die; if the embryo hatches it will be a male with a diploid (2n) number of chromosomes.
Parthenogenesis (from the Greek παÏθενος parthenos, "virgin", + γενεσις genesis, "birth") describes the growth and development of an embryo or seed without fertilization by a male. Parthenogenesis occurs naturally in some species, including lower plants (called agamospermy), invertebrates (e.g. water fleas, aphids, some bees and parasitic wasps), and vertebrates (e.g. some reptiles, fish, and, very rarely, birds).
