Aposematic color polymorphism is a poor indicator of species boundaries in North American Paranthrene (Lepidoptera: Sesiidae) as evidenced by a multi-gene phylogeny. [PDF]

PLoS ONE
Color polymorphism among animal species can influence speciation. Factors such as natural and sexual selection, genetic drift and gene flow contribute to the maintenance of color polymorphism within the species or spur speciation.

Genetics of Color Polymorphism in the Pea Aphid,Acyrthosiphon pisum [PDF]

Journal of Insect Science, 2010
The genetic basis of color polymorphism is explored in the pea aphid, Acyrthosiphon pisum (Harris) (Homoptera: Sternorrhyncha), in which two color morphs have been described (pink or green). Laboratory crosses and a Mendelian genetic analysis reveal that color polymorphism in pea aphids is determined by a single biallelic locus, which we name colorama,

Structural background of intraspecific color polymorphism and the driver of geographic patterns in a shining leaf chafer [PDF]

Frontiers in Zoology
Background The phenomenon of color polymorphism has been extensively documented in a range of animal species. A series of hypotheses have been proposed to explain potential functions of color variations in diverse habitats.

Genetic Control of Tissue Remodeling by a Non‐Coding SNP in ITGA8 Explains Carotenoid‐Based Color Polymorphism in Marine Mollusks [PDF]

Advanced Science
Biological color polymorphism represents a widespread form of phenotypic diversity in nature; however, the multi‐scale regulatory mechanisms of carotenoid‐based coloration, from genetic control to cell states and tissue architecture, remain poorly ...

Chromosome replacement and deletion lead to clonal polymorphism of berry color in grapevine. [PDF]

PLoS Genetics, 2015
Clonal polymorphism mainly results from somatic mutations that occur naturally during plant growth. In grapevine, arrays of clones have been selected within varieties as a valuable source of diversity, among them clones showing berry color polymorphism ...

Color polymorphic carnivores have faster speciation rates [PDF]

Scientific Reports
Variation in coat color is a prominent feature in carnivores, thought to be shaped by environmental factors. As new traits could allow populations to occupy novel niches and habitats, color polymorphism may be maintained by balancing selection ...

Pollinator response to flower color polymorphism and floral display in a plant with a single‐locus floral color polymorphism: consequences for plant reproduction [PDF]

Ecological Research, 2011
Abstract Variation in flower color, particularly polymorphism, in which two or more different flower color phenotypes occur in the same population or species, may be affected or maintained by mechanisms that depend on pollinators.

Trait differences among discrete morphs of a color polymorphic lizard, Podarcis erhardii [PDF]

PeerJ, 2020
Color polymorphism defies evolutionary expectations as striking phenotypic variation is maintained within a single species. Color and other traits mediate social interactions, and stable polymorphism within a population is hypothesized to be related to ...

Dominant gingers – Discovery and inheritance of a new shell polymorphism in the great pond snail Lymnaea stagnalis

Ecology and Evolution, 2023
Color polymorphism is a classic study system for evolutionary genetics. One of the most color‐polymorphic animal taxa is mollusks, but the investigation of the genetic basis of color determination is often hindered by their life history and the limited ...

Colorful DNA polymorphisms in humans [PDF]

Seminars in Cell & Developmental Biology, 2013
In this review article we summarize current knowledge on how variation on the DNA level influences human pigmentation including color variation of iris, hair, and skin. We review recent progress in the field of human pigmentation genetics by focusing on the genes and DNA polymorphisms discovered to be involved in determining human pigmentation traits ...
