Evidence: 100 • authority: 72

Albinism is the congenital absence of pigmentation (in mammals, melanin) in an animal or plant resulting in "hair being white, red, or yellow", "feathers, scales, and skin being yellow", "eyes being red, pink, purple, violet, or blue", and "leaves or stems being white or yellow", if applicable. Individuals with the condition are referred to as albinos. Varied use and interpretation of the terms mean that written reports of albinistic animals can be difficult to verify. Albinism can reduce the survivability of an animal; for example, it has been suggested that albino alligators have an average survival span of only 24 years due to the lack of protection from UV radiation and their lack of ca…

&lt;span&gt;ASEAN Centrality in the Era of Great Power Competition:&lt;/span&gt;&lt;span&gt;Hedging for Survival and Prosperity&lt;/span&gt;. <div> The Association of Southeast Asian Nations (ASEAN) was formed in 1967 with the Bangkok Conference as a bulwark against the spread of Communism in Southeast Asia.

A stock character is a dramatic or literary character representing a generic type in a conventional, simplified manner and recurring in many fictional works. The following list labels some of these stereotypes and provides examples. Some character archetypes, the more universal foundations of fictional characters, are also listed. Some characters that were first introduced as fully fleshed-out characters become subsequently used as stock characters in other works – for example, the Ebenezer Scrooge character from A Christmas Carol, upon whom the "miser" stereotype is based, and whose name now has become a shorthand for it. Some stock characters incorporate more than one stock character; for…

Candidate genes underlying hypomelanistic morphs in squamate reptiles.. Skin coloration is crucial for the survival of animals and ranges from spectacular colorful displays used to attract a mate to cryptic camouflage used to avoid predators. Among the 3 main types of chromatophores, melanophores are the most widespread in vertebrates and can set the skin tone by the amount of melanin they produce and store in dedicated vesicles, the melanosomes. Mutations associated with melanophore differentiation and maturation result in hypomelanistic and amelanistic phenotypes, both extensively studied in mammals but less so in snakes and lizards. Here, we characterize at the genomic, transcriptomic, a…
