• Vocabulary: Phenotypic Plasticity — the remarkable ability of a single, identical genotype to produce multiple distinct phenotypes in direct response to shifting environmental conditions [cite: 13, 14].
• Concept: External factors such as temperature, sunlight, and soil chemistry can influence the expression of genes and resulting phenotypes.
