This is a three-part activity that introduces the concept of genetic diversity within a population. In Part I students will observe and compare human traits within their classroom population, demonstrating that each individual has a variety of traits that make him or her unique and that create a diverse population. In Part II they will discover through a quick, active demonstration that increased diversity contributes to greater survivability. Part III reinforces this idea that these same concepts can be seen in a white-tailed deer population coping with changes in the environment over time.
