Lesson 5: Environmental Effects on Phenotype
Duration of Days: 1
Lesson Objective
Explain how the same genotype can result in multiple phenotypes for a given organism depending on environmental conditions.
How can external environmental factors like temperature, pH, or diet alter gene expression without altering the DNA sequence?
What is phenotypic plasticity, and how does it benefit an organism's survival?
5.5-Environmental Effects on Phenotype
Demonstrate that an organism's physical traits (phenotype) are not determined by its DNA sequence alone, but are often the result of environmental factors interacting with those genes.
