Which statement best describes the role of heredity in child development?

• A. Heredity influences physical characteristics and temperament
• B. Heredity determines all future decisions
• C. Heredity has no impact
• D. Heredity only affects height

Answer: (A)

Heredity provides a biological blueprint that shapes who a child is, especially physical traits like height, eye and hair color, and baseline temperament. The genes a child inherits from parents influence these aspects, forming a foundation for development. At the same time, environment and experiences interact with these genetic tendencies, shaping how traits express themselves and influence later behavior and decisions. So, describing heredity as influencing physical characteristics and temperament best captures how genetic factors contribute to development. The idea that heredity determines all future decisions overstates its role, and saying it has no impact or only affects height ignores the broad influence genes have on many traits and tendencies.
