Topic 5.5: Environmental Effects on Phenotype
Learning Objective: 5.5.A
Explain how the same genotype can result in multiple phenotypes under different environmental conditions.
Essential Knowledge: 5.5.A.1
Environmental conditions influence gene expression and can lead to phenotypic plasticity (e.g., the ability of individual genotypes to produce different phenotypes). Illustrative examples: Height and weight in humans; Flower color based on soil pH; Seasonal fur color in arctic animals; Sex determination in reptiles; Effect of increased UV on melanin production in animals; Presence of the opposite mating type on pheromone production in yeast and other fungi.
