3. Heredity or the Environment? Briefly explain your answer.

The question of "nature versus nurture" (heredity versus environment) is complex, and the answer is almost always **both**. While heredity provides the genetic blueprint for traits like eye color, height, and predisposition to certain diseases, the environment plays a crucial role in how these traits are expressed. For example, a child might inherit genes for tall stature, but malnutrition could stunt their growth. Similarly, someone might have a genetic predisposition to heart disease, but a healthy diet and exercise can significantly reduce their risk. Our genes provide the potential, but the environment influences how that potential is realized.
