  2. 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.

  3. 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).

    Gynogenesis with haplodiploidy in the ant Myrmecia impaternata. The ant Myrmecia impaternata is a hybrid of M. banksi and M. pilosula. [7] In ants, sex is determined by the haplodiploidy system: unfertilized eggs result in haploid males, while fertilized eggs result in diploid females.

  6. Parthenogenesis in amphibians - Wikipedia

    en.wikipedia.org/wiki/Parthenogenesis_in_Amphibians

    Parthenogenesis is a form of reproduction where eggs develop without fertilization, resulting in unisexual species. This phenomenon is closely related with reproductive modes such as hybridogenesis, where fertilization occurs, but the paternal DNA is not passed on.

  7. Fish reproduction - Wikipedia

    en.wikipedia.org/wiki/Fish_reproduction

    The eggs have an average diameter of 1 millimetre (0.039 in). The eggs are generally surrounded by the extraembryonic membranes but do not develop a shell, hard or soft, around these membranes. Some fish have thick, leathery coats, especially if they must withstand physical force or desiccation. These type of eggs can also be very small and ...

  8. Sequential hermaphroditism - Wikipedia

    en.wikipedia.org/wiki/Sequential_hermaphroditism

    In a paired mating system (one male mates with one female, such as in clownfish or moray eels) the male can only fertilize one batch of eggs, whereas the female needs only a small male to fertilize her batch of eggs. so the larger she is, the more eggs she'll be able to produce and have fertilized.

  9. Female sperm storage - Wikipedia

    en.wikipedia.org/wiki/Female_Sperm_Storage

    Sperm storage organs in the fruit fly Drosophila melanogaster.Female was first mated with GFP-male and then re-mated with RFP-male. Female sperm storage is a biological process and often a type of sexual selection in which sperm cells transferred to a female during mating are temporarily retained within a specific part of the reproductive tract before the oocyte, or egg, is fertilized.
