  2. Hybrid speciation - Wikipedia

    en.wikipedia.org/wiki/Hybrid_speciation

    Two species mate resulting in a fit hybrid that is unable to mate with members of its parent species. Hybrid speciation is a form of speciation where hybridization between two different species leads to a new species, reproductively isolated from the parent species. Previously, reproductive isolation between two species and their parents was ...

  3. List of genetic hybrids - Wikipedia

    en.wikipedia.org/wiki/List_of_genetic_hybrids

    The naming of hybrid animals depends on the sex and species of the parents. The father giving the first half of his species' name and the mother the second half of hers. (I.e. a pizzly bear has a polar bear father and grizzly bear mother whereas a grolar bear's parents would be reversed.)

  4. Heterothallism - Wikipedia

    en.wikipedia.org/wiki/Heterothallism

    Sexual fruiting bodies (perithecia) can only be formed when two mycelia of different mating type come together. Like other ascomycetes, N. crassa has two mating types that, in this case, are symbolized by ‘A’ and ‘a’. There is no evident morphological difference between the ‘A’ and 'a' mating type strains.

  5. Hybrid (biology) - Wikipedia

    en.wikipedia.org/wiki/Hybrid_(biology)

    A mule is a sterile hybrid of a male donkey and a female horse.Mules are smaller than horses but stronger than donkeys, making them useful as pack animals.. In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction.

  6. Mating in fungi - Wikipedia

    en.wikipedia.org/wiki/Mating_in_fungi

    Sexual fruiting bodies (perithecia) can only be formed when two cells of different mating type come together (see Figure). Like other Ascomycetes, N. crassa has two mating types that, in this case, are symbolized by A and a. There is no evident morphological difference between the A and a mating type strains. Both can form abundant ...

  7. F1 hybrid - Wikipedia

    en.wikipedia.org/wiki/F1_hybrid

    Two savannah cats, a hybrid between the domestic cat (Felis catus) and the serval (Leptailurus serval). The larger of the two is an F1 hybrid, while the smaller is an F4 hybrid. F1 hybrid (also known as filial 1 hybrid) is the first filial generation of offspring of distinctly different parental types. [1]

  8. Ursid hybrid - Wikipedia

    en.wikipedia.org/wiki/Ursid_hybrid

    Possible hybridisation between different species of bear. An ursid hybrid is an animal with parents from two different species or subspecies of the bear family (Ursidae).Species and subspecies of bear known to have produced offspring with another bear species or subspecies include American black bears, grizzly bears, and polar bears, all of which are members of the genus Ursus.

  9. Reinforcement (speciation) - Wikipedia

    en.wikipedia.org/wiki/Reinforcement_(speciation)

    Servedio and Noor include any detected increase in prezygotic isolation as reinforcement, as long as it is a response to selection against mating between two different species. [4] Coyne and Orr contend that, "true reinforcement is restricted to cases in which isolation is enhanced between taxa that can still exchange genes". [3]: 352
