Concept:Individual differences arise from the joint action of hereditary and environmental factors.
Explanation:A child’s genetic makeup is inherited from parents, but the environment shapes how those genes are expressed.
Heredity sets the potential limits, while environment determines the actual development within those limits.
The two factors are not independent; they interact in a complex, productive way.
For example, inborn traits (IQ, aptitude) depend mainly on heredity, but mental and social skills depend largely on environment.
Thus, both together produce individual variations.
