Final answer:
True, Phenotypic plasticity is when individuals with identical genotypes have different phenotypes due to different environments. It is influenced by both genetics and the environment and is important for adaptation and evolution.
Step-by-step explanation:
Phenotypic plasticity refers to the phenomenon where individuals with the same genetic makeup can exhibit different traits or phenotypes when living in different environments. This is influenced by both genetic and environmental factors, and it plays an important role in how populations adapt and evolve over time. For example, a plant species with the same genotype may have different leaf shapes or sizes depending on whether it grows in a sunny or shady area. In summary, phenotypic plasticity allows organisms to adjust their traits in response to environmental conditions.
