polyphenism
A biological term referring to the phenomenon where a single genotype produces multiple distinct phenotypes in response to environmental conditions. Used in genetics and evolutionary biology.
Polyphenism refers to the phenomenon where different phenotypes arise from the same genotype depending on the environment.
多型 (polymorphism) is a broader term for variation within a population, while 表現型多型 specifically refers to environmentally induced phenotypic variation from a single genotype.
Compound of 表現型 (phenotype) and 多型 (polymorphism). The exact historical derivation is uncertain; the term is a modern scientific coinage.
