Polyphenism
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 … Webfemale wing polyphenism (fs-2, arose first) and its genetic assimilation in males (fs-3, arose second).
