Mosaic canaries are strongly sexually dichromatic. In an effort to understand how sexual dichromatism is produced from a nearly identical set of genes, evolutionary biologist Małgorzata Gazda and ...

Most remarkable of all, though, are the frogs exhibiting dynamic dichromatism. They change color every mating season but then revert back to their old selves.

Examples of dichromatism in fact were one of the issues that lead him to develop his theory of sexual selection, where elaborate male traits could evolve through female preference for conspicuous ...

DICHROMATISM, or the change of colour of an absorbing medium with increasing thickness, is usually shown with plates of coloured glass. It is not always easy to obtain the right kind of glass, and ...

Mapping of dichromatism in Characiformes. Approximately 1,750 species live in South America, and the rest live in Africa. Their size ranges from 1.7 cm to 2 m.

From National Geographic Wild, how male peacocks try to impress females by strutting their stuff. But you don't have to look further than your back garden to see sexual dichromatism for yourself.

Female birds often sport less colorful plumage than males of the same species. Some birds evolved this sexual dichromatism as an adaptation related to mating and survival, but scientists still don ...
