Poecilia picta, a Close Relative to the Guppy, Exhibits Red Male Coloration Polymorphism: A System for Phylogenetic Comparisons. [PDF]

PLoS ONE, 2015
Studies on the evolution of female preference and male color polymorphism frequently focus on single species since traits and preferences are thought to co-evolve.

Trade-Offs Associated with Photoprotective Green Fluorescent Protein Expression as Potential Drivers of Balancing Selection for Color Polymorphism in Reef Corals

Frontiers in Marine Science, 2018
Photodamage of symbiotic algae exposed to thermal stress is involved in mass coral bleaching, a major cause of reef decline. Photoprotection is therefore a vital part of coral stress physiology. Corals produce a variety of green fluorescent protein (GFP)-

Polymorphism of fur coloration intensity in mammals [PDF]

Proceedings of the Theriological School, 2016
The concept of coloration polymorphism and melanism in mammals was reviewed. It was shown that polymorphism has different types and mammals color differentiation is only one of its kinds. Three classic hypotheses on the function of coloration in mammals are known: concealment, communication, and regulation of physiological processes.

Identification of shell-color-related microRNAs in the Manila clam Ruditapes philippinarum using high-throughput sequencing of small RNA transcriptomes

Scientific Reports, 2021
Shell-color polymorphism is a common phenomenon in several mollusk species and has been associated with thermal capacity, developmental stability, shell strength, and immunity.

Analysis of protein kinase C (HcPKC) gene expression and single-nucleotide polymorphisms related to inner shell color traits in Hyriopsis cumingii

BMC Genomic Data, 2022
Background Protein kinase C (PKC) is a multifunctional serine and PKC can phosphorylate serine residues in the cytoplasmic domain of tyrosinase, thereby regulating the activity of tyrosinase.

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 ...

Detection of Snps in the Melanocortin 1-Receptor (MC1R) and Its Association with Shank Color Trait in Hs Chicken [PDF]

Brazilian Journal of Poultry Science, 2019
The melanocortin 1 receptor (MC1R) gene plays a key role in controlling the deposition of melanin. In mammals, the MC1Rgene is regarded as a major candidate gene in the control of melanin formation.

Phenotypic and molecular variation in the green and black poison-dart frog Dendrobates auratus (Anura: Dendrobatidae) from Costa Rica

Revista de Biología Tropical, 2009
The green and black poison-dart frog Dendrobates auratus exhibits high intraspecific variation in hue color and pattern throughout its range, making it a very popular species in the pet trade.
