Polymorphism_(biology)

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 … A polyphenic trait is a trait for which multiple, discrete phenotypes can arise from a single genotype as a result of differing environmental conditions. It is therefore a special case of phenotypic plasticity. There are several types of polyphenism in animals, from having sex determined by the environment to the … See more A polyphenism is the occurrence of several phenotypes in a population, the differences between which are not the result of genetic differences.
