WebPolymorphism in biology occurs when two or more clearly different types exist in the same population of the same species — in other words, the occurrence of more than one form or morph.The caste system in ants is an example.. Polymorphism (Greek: poly = many, and morph = form) is defined as discontinuous variation in a single population — meaning, the … WebApr 1, 2024 · Such phenotypic plasticity is referred to as polyphenism. Seasonal, dispersal and caste polyphenisms correspond to the most-studied examples that are environmentally-induced in insects. Cues that induce such dramatic phenotypic changes are very diverse, ranging from seasonal cues, habitat quality changes or differential larval nutrition.
WebJun 28, 2008 · The results suggest that, while foraging, the overall strategy is to use polyphenism to produce ‘apparent rarity’ of any single phenotype (or search image) through mechanisms of crypsis, conspicuousness and mimicry, all of which are guided by keen vision in this marine invertebrate.
