1. Gilbert’s genetic makeup is homozygous for dark hair. Jan’s is homozygous for blond hair. What color is Gilbert’s hair? How about Jan’s?

2. Referring to ecological systems theory, explain why parents of children with genetic disorders often experience increased stress. What factors, within and beyond the family, can help these parents support their children’s development?

3. Explain the genetic origins of PKU and Down syndrome. Cite evidence that both heredity and environment contribute to the development of individuals with these disorders.

4. Bianca’s parents are accomplished musicians. At age 4, Bianca began taking piano lessons. By age 10, she was accompanying the school choir. At age 14, she asked if she could attend a special music high school. Explain how genetic–environmental correlation promoted Bianca’s talent.

5. What aspects of your own development—for example, interests, hobbies, college major, or vocational choice—are probably due to niche-picking? Explain.

"Almost 30 years ago, developmental psychologist Sandra Scarr and colleagues set forth the notion that our genetic predispositions lead us, perhaps, to gravitate toward certain activities- sports, music, dance, math, and so on. (niche-picking) Once we start to become involved in these activities, we develop further those qualities that led us there in the first place. The kid who loves baseball eventually perfects a mighty swing. The cartwheel-loving tot ends up winning balance beam competitions 10 years later as she develops her strength and agility. Potential abilities that were at one time influenced in some way by a particular DNA combo now flourish through training, dedication, and education."

6. Imagine that you are a woman who is a carrier of fragile X syndrome but who wants to have children.
