Explain how, according to Piaget, heredity and experience both contribute to intellectual growth.

In simple words, The interaction of heredity and life experience has an impact on an individual's intellect. The maximum and minimum IQs that a person can achieve are determined by hereditary factors. The experience determines where a person's IQ falls between these parameters. Many investigations, however, show that hereditary variables account for roughly half of the variance in IQ between people.
