  2. List of taxa that use parthenogenesis - Wikipedia

    en.wikipedia.org/wiki/List_of_taxa_that_use...

    In bdelloid rotifers, females reproduce exclusively by parthenogenesis (obligate parthenogenesis), [5] while in monogonont rotifers, females can alternate between sexual and asexual reproduction (cyclical parthenogenesis). At least in one normally cyclical parthenogenetic species obligate parthenogenesis can be inherited: a recessive allele ...

  3. Parthenogenesis - Wikipedia

    en.wikipedia.org/wiki/Parthenogenesis

    Parthenogenesis (/ ˌ p ɑːr θ ɪ n oʊ ˈ dʒ ɛ n ɪ s ɪ s,-θ ɪ n ə-/; [1] [2] from the Greek παρθένος, parthénos, 'virgin' + γένεσις, génesis, 'creation' [3]) is a natural form of asexual reproduction in which the embryo develops directly from an egg without need for fertilization.

  4. Asexual reproduction - Wikipedia

    en.wikipedia.org/wiki/Asexual_reproduction

    Clonal Fragmentation in multicellular or colonial organisms is a form of asexual reproduction or cloning where an organism is split into fragments. Each of these fragments develop into mature, fully grown individuals that are clones of the original organism. In echinoderms, this method of reproduction is usually known as fissiparity. [18]

    A boa constrictor in the U.K. gave birth to 14 babies — without a mate. The process is called parthenogenesis, from the Greek words for “virgin” and “birth.” It tends to occur in ...

  6. Parthenogenesis in squamates - Wikipedia

    en.wikipedia.org/wiki/Parthenogenesis_in_squamates

    Parthenogenesis is a mode of asexual reproduction in which offspring are produced by females without the genetic contribution of a male. Among all the sexual vertebrates, the only examples of true parthenogenesis, in which all-female populations reproduce without the involvement of males, are found in squamate reptiles (snakes and lizards). [1]

  7. Thelytoky - Wikipedia

    en.wikipedia.org/wiki/Thelytoky

    Aphid giving birth by parthenogenesis, the live young growing from unfertilized eggs. Thelytoky (from the Greek θῆλυς thēlys "female" and τόκος tókos "birth") is a type of parthenogenesis and is the absence of mating and subsequent production of all female diploid offspring as for example in aphids.

  8. Parthenogenesis in amphibians - Wikipedia

    en.wikipedia.org/wiki/Parthenogenesis_in_Amphibians

    Kleptogenesis is a sexually parasitic form of reproduction in unisexual organisms, that is often associated with species that are also capable of gynogenetic reproduction. [8] In this reproductive mode unisexual females mate with sympatric males of related species, and genetic material in the paternal line recombines with the maternal DNA and ...

  9. Bdelloidea - Wikipedia

    en.wikipedia.org/wiki/Bdelloidea

    Bdelloids are of interest in the study of the evolution of sex because a male has never been observed, [20] and females reproduce exclusively by parthenogenesis, [broken anchor] a form of asexual reproduction where embryos grow and develop without the need for fertilization; this is akin to the apomixis seen in some plants.
