    Asexual reproduction is a type of reproduction that does not ... Many protists and fungi alternate between sexual and asexual reproduction. A few species of ...

  3. Parthenogenesis - Wikipedia

    en.wikipedia.org/wiki/Parthenogenesis

    This form of asexual reproduction is thought in some cases to be a serious threat to biodiversity for the subsequent lack of gene variation and potentially decreased fitness of the offspring. [ 39 ] Some invertebrate species that feature (partial) sexual reproduction in their native range are found to reproduce solely by parthenogenesis in ...

  4. 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]

  5. 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 ...

  6. Reproduction - Wikipedia

    en.wikipedia.org/wiki/Reproduction

    There are two forms of reproduction: asexual and sexual. In asexual reproduction, an organism can reproduce without the involvement of another organism. Asexual reproduction is not limited to single-celled organisms. The cloning of an organism is a form of asexual reproduction. By asexual reproduction, an organism creates a genetically similar ...

  7. Gynogenesis - Wikipedia

    en.wikipedia.org/wiki/Gynogenesis

    Gynogenesis, a form of parthenogenesis, is a system of asexual reproduction that requires the presence of sperm without the actual contribution of its DNA for completion. . The paternal DNA dissolves or is destroyed before it can fuse with the egg

  8. Fragmentation (reproduction) - Wikipedia

    en.wikipedia.org/wiki/Fragmentation_(reproduction)

    Fragmentation in multicellular or colonial organisms is a form of asexual reproduction or cloning, where an organism is split into fragments upon maturation and the split part becomes the new individual. The organism may develop specific organs or zones to shed or be easily broken off.

  9. Mammalian reproduction - Wikipedia

    en.wikipedia.org/wiki/Mammalian_reproduction

    Male mammals ejaculate semen through the penis into the female reproductive tract during copulation. [28] [29] Ejaculation usually occurs after only one intromission in humans, canids, and ungulates, but occurs after multiple intromissions in most mammal species. [30] [31] Copulation can induce ovulation in mammal species that do not ovulate ...
