  2. Asexual reproduction - Wikipedia

    en.wikipedia.org/wiki/Asexual_reproduction

    Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes. The offspring that arise by asexual reproduction from either unicellular or multicellular organisms inherit the full set of genes of their single parent and thus the newly created individual is genetically and ...

  3. Plant reproduction - Wikipedia

    en.wikipedia.org/wiki/Plant_reproduction

    Asexual reproduction in plants occurs in two fundamental forms, vegetative reproduction and agamospermy. [1] Vegetative reproduction involves a vegetative piece of the original plant producing new individuals by budding, tillering , etc. and is distinguished from apomixis , which is a replacement of sexual reproduction, and in some cases ...

  4. Parthenogenesis - Wikipedia

    en.wikipedia.org/wiki/Parthenogenesis

    A form of asexual reproduction related to parthenogenesis is gynogenesis. Here, offspring are produced by the same mechanism as in parthenogenesis, but with the requirement that the egg merely be stimulated by the presence of sperm in order to develop. However, the sperm cell does not contribute any genetic material to the offspring.

  5. Androgenesis - Wikipedia

    en.wikipedia.org/wiki/Androgenesis

    Androgenesis is a system of asexual reproduction that requires the presence of eggs and occurs when a zygote is produced with only paternal nuclear genes.During standard sexual reproduction, one female parent and one male parent each produce haploid gametes (such as a sperm or egg cell, each containing only a single set of chromosomes), which recombine to create offspring with genetic material ...

  6. Vegetative reproduction - Wikipedia

    en.wikipedia.org/wiki/Vegetative_reproduction

    Vegetative reproduction (also known as vegetative propagation, vegetative multiplication or cloning) is a form of asexual reproduction occurring in plants in which a new plant grows from a fragment or cutting of the parent plant or specialized reproductive structures, which are sometimes called vegetative propagules.

  7. Pseudogamy - Wikipedia

    en.wikipedia.org/wiki/Pseudogamy

    Apomixis in flowering plants (angiosperms) includes some types of vegetative reproduction and also agamospermy, which is asexual reproduction through seeds [9] (see apomixis for more information). Agamospermy can occur through many different mechanisms, [ 6 ] [ 7 ] some of which require pollination (pseudogamy), and some of which do not ...

  8. Apomixis - Wikipedia

    en.wikipedia.org/wiki/Apomixis

    Agamospermy, asexual reproduction through seeds, occurs in flowering plants through many different mechanisms [4] and a simple hierarchical classification of the different types is not possible. Consequently, there are almost as many different usages of terminology for apomixis in angiosperms as there are authors on the subject.

  9. Cloning - Wikipedia

    en.wikipedia.org/wiki/Cloning

    This is an asexual form of reproduction that is only found in females of some insects, crustaceans, nematodes, [24] fish (for example the hammerhead shark [25]), Cape honeybees, [26] and lizards including the Komodo dragon [25] and several whiptails. The growth and development occurs without fertilization by a male.
