  2. List of polymorphisms - Wikipedia

    en.wikipedia.org/wiki/List_of_polymorphisms

    All the flies look alike whatever inversions they carry: this is an example of a cryptic polymorphism. Accordingly, Dobzhansky favoured the idea that the morphs became fixed in the population by means of Sewall Wright's drift. [54] However, evidence rapidly accumulated to show that natural selection was responsible: Drosophila polytene ...

  3. Polymorphism (biology) - Wikipedia

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

    In biology, polymorphism [1] is the occurrence of two or more clearly different morphs or forms, also referred to as alternative phenotypes, in the population of a species. To be classified as such, morphs must occupy the same habitat at the same time and belong to a panmictic population (one with random mating).

  4. Batesian mimicry - Wikipedia

    en.wikipedia.org/wiki/Batesian_mimicry

    In Batesian mimicry, the mimic effectively copies the coloration of an aposematic animal, known as the model, to deceive predators into behaving as if it were distasteful. [ a ] The success of this dishonest display depends on the level of toxicity of the model and the abundance of the model in the geographical area.

  5. Gene polymorphism - Wikipedia

    en.wikipedia.org/wiki/Gene_polymorphism

    One example is the gene CD14, which is known to have a polymorphism that is associated with increased amounts of CD14 protein as well as reduced levels of IgE serum. [30] A study was conducted on 624 children looking at their IgE serum levels as it related to the polymorphism in CD14.

  6. Chromosomal polymorphism - Wikipedia

    en.wikipedia.org/wiki/Chromosomal_polymorphism

    Trichomycterus davisi, for example, is an extreme case where the polymorphism was present within a single chimeric individual. [1] It has also been studied in alfalfa, [2] shrews, [3] Brazilian rodents, [4] and an enormous variety of other animals and plants. [5] In one instance it has been found in a human. [6]

  7. Aggressive mimicry - Wikipedia

    en.wikipedia.org/wiki/Aggressive_mimicry

    This example of acoustic aggressive mimicry is similar to the Photuris firefly case in that the predator's mimicry is remarkably versatile – playback experiments show that C. leucoviridis is able to attract males of many cicada species, including Cicadettine cicadas from other continents, even though cicada mating signals are species-specific.

    Animals such as birds and humans have different docking stations on their cells — known as sialic acid receptors. In order for a flu virus to open a door into a cell and begin replicating, it ...

  9. Polymorphism in Lepidoptera - Wikipedia

    en.wikipedia.org/wiki/Polymorphism_in_Lepidoptera

    Polymorphic and/or mimetic females occur in the case of some taxa in the Papilionidae primarily to obtain a level of protection not available to the male of their species. The most distinct case of sexual dimorphism is that of adult females of many Psychidae species who have only vestigial wings, legs, and mouthparts as compared to the adult ...
